Technology is changing fast, and to become complacent is to risk irrelevance. Here are some of the methods I use to keep in touch with how technology is ever changing:

• Participating in Experts-Exchange. This has me answering questions in a wide range of technological areas. To solve many of these problems I need to research the solution, and try it out on my own before posting an appropriate response. This gives me a lot of hands on experience and keeps me finding new and different solutions to ever changing problems of the computer world.
• Subscribing to multiple Microsoft blogs via RSS on MSDN and Technet, such as the Microsoft Security Response Center blog. I read blogs like these daily to get the latest information on what is going on in the industry. By setting these kind of blogs onto my homepage with an RSS reader I am able to get information from multiple sources and read further about titles that interest me. I also subscribe to email alerts, such as the Microsoft Security bulletin to keep up with new security threats to PC systems. Microsoft doesn’t dominate the blogosphere, however, and other great blogs that I subscribe to including Google’s Matt Cutts. He posts a lot of innovative information about google and other search engine topics.
• Using and participating in organizations that promote technology standards. I am a large proponent of HTML standardization and other such efforts to bring standards to technology implementation.
• Using multiple web browsers. As of this post I have Internet Explorer 8 beta, Firefox 3, Google Chrome and Apple Safari for Windows. Right now I use Chrome, but as updates are added to other browsers, I may change. For a long time I used IE and then switched to Firefox before settling on Chrome when it was released. I use these installs to verify how webpages I code appear in different browsers. This is also very helpful when trying to solve a browser specific issue for a friend or on Experts-Exchange.
• Furthering my education, by working on technological certifications. The biggest one I am working on right now is the Microsoft Certified Systems Engineer certification. More will definitely come after that one is completed.

How do you stay up to date?
