Apple's stock fell abruptly on Tuesday, but later recovered some ground, after an online report said CEO Steve Jobs bowed out of next week's Macworld Expo keynote address because of declining health.

In a report it labeled "rumor," the gadget blog Gizmodo quoted an unnamed source as saying Apple "is choosing to remove the hype factor strategically" by holding the keynote without Jobs, whose "health is rapidly declining." Gizmodo said the source had been correct in the past, though only about Apple products and not about Jobs. Apple did not comment for the Gizmodo post and did not immediately respond to IDG News Service requests for comment.

Apple's Nasdaq stock (AAPL), which had closed at $86.61 on Monday, fell as low as $84.72, a drop of about 2 percent. But shares ended the day at $86.29, down just $0.32, or 0.37 percent.

Apple announced on Dec. 16 that Phil Schiller, senior vice president of worldwide product marketing, would deliver the keynote at Macworld Expo in San Francisco on Jan. 6. For many years since he returned to Apple in 1997, Jobs has given that speech and used it as a launch platform for important products, including the iPhone in 2007 and the MacBook Air in 2008.

At the same time, Apple said it would stop exhibiting at Macworld Expo after the January event. The company said trade shows had become a minor part of its marketing strategy.

Concerns have been raised about Jobs's health since his appearance at Apple's Worldwide Developer Conference in June, when some observers said he appeared gaunt. Jobs said in 2004 that he had undergone surgery for pancreatic cancer. On Oct. 3, Apple shares fell more than 10 percent after a report that Jobs had suffered a major heart attack. The stock recovered after Apple said the report, from a "citizen journalist" on an unfiltered section of CNN's Web site, wasn't true.

Master these Web sites, and you’ll prove you can innovate during the most trying economic times. And you’ll do it more efficiently than your 20-something employees, who waste too much time chasing the new, new thing on the Internet that may not survive the downturn.

1. LinkedIn
Forget Facebook. In the last six months, LinkedIn has become the de rigueur Web 2.0 site for IT professionals. LinkedIn has 30 million members, almost double what it had a year ago. And it raised more than $75 million in venture capital during 2008, so it has staying power. It has a host of new features that make it the most productive networking site on the Web. Spend some time updating your LinkedIn profile and reaching out to current and former colleagues. You can show your boss that you’re well connected, and you’ll be ready in case you’re on the next layoff list. In 2008, LinkedIn made our list of the 20 most useful social networking sites on the Web.

2. Google Apps for Business
Call it what you like – software as a service or cloud computing – but it’s the future of enterprise IT departments, and you need to get on board with it. You’ll be under more pressure than ever in 2009 to find cheaper ways to deliver IT services. One way to do that is to pilot a Google Apps project, such as document sharing via GoogleDocs or video sharing via Google Video. Your staff can build one of these collaboration projects in a jiffy, and the information will be available to employees from any location on any computer. Among Google Apps proponents: The District of Columbia government. 

3. VMware Communities
Chances are you’ve already embarked on a server virtualization project, and continued consolidation of your servers is a key money-saving goal for 2009. Most of you are using VMware for your server virtualization projects, and our product reviewers recommend you stick with VMware over Microsoft’s Hyper-V for the foreseeable future. To get the best real-world feedback on how best to deploy VMware, keep your eyes on the VMware Communities Web site. It’s got user groups in your community and lots of tips from other VMware developers that can help you solve problems faster.

4. Secunia
Security will continue to be a top priority for 2009, but you’ll need to figure out how to do it on the cheap. That’s where Secunia.com comes in. This site aggregates security vulnerability information from leading vendors, providing you with one-stop shopping for the latest news about security bugs and the software patches available to fix them. The site has an active community of IT security folks who can help you fix operating systems and applications before you get attacked.

5. Green Grid
With the economy in shambles and energy prices plummeting, you’re likely to hear a lot less about global climate change and carbon neutral business operations than you did six months ago. Nonetheless, green IT can still be a huge advantage for IT departments because it will save you money. Plain and simple: Green IT saves greenbacks. So get to know the Green Grid’s Web site and make sure that whatever you buy in 2009 for your datacenters is in line with their advice and metrics. Here’s more information about the Green Grid along with three other organizations that offer advice about lowering datacenter power consumption.

6. Twitter
At first glance, Twitter seems like a colossal waste of time. But the fact is this real-time messaging service is taking off in IT circles. And if you don’t jump on the bandwagon soon, you might be too late. Twitter provides an easy way to keep your staff and coworkers informed about where you are and what you’re doing. You can also sign up for the latest technology headlines from Wired, Slashdot, and others. It doesn’t take long to sign up for Twitter – give it a whirl so that you’ll know what your Generation Y employees are talking about. See 20 must-follow Twitter feeds here.

7. Yammer
If Twitter seems too frivolous to you, try Yammer. It’s essentially Twitter for the office. The benefit of Yammer is that it’s a private communications channel for coworkers to share quick messages about what they’re working on, get questions answered, or blast out news. Xerox and Cisco are among the 200-plus companies enjoying improved collaboration thanks to Yammer. One benefit of Yammer over Twitter: It seems to have a sustainable business model. 

8. Ruby on Rails
Ruby on Rails is one of the best open source tools to appear in recent years. This Web development framework lets you create working applications in a matter of hours. Advocates of this development platform include the New York Times, Yellowpages.com, Twitter, and Hulu. See 15 amazing Web applications built with Ruby on Rails here. Version 2.2 of Ruby on Rails came out in November, so you don’t have to worry about being on the bleeding edge.

9. Enterprise Mobility Matters
Like it or not, the latest smartphones – the BlackBerry Storms and Apple 3G iPhones (slideshow: Smartphone showdown: iPhone vs. BlackBerry Storm ) – are headed toward your corporate network. So you better get ready to protect sensitive corporate information from the risks that these consumer devices open up. If you don’t want to encrypt them, make sure you have centralized control over them so that you can wipe data from lost or stolen cell phones. We like the Enterprise Mobility Matters Web site from market research firm Strategy Analytics because it offers a comprehensive look at enterprise mobility issues.
