Microsoft has launched “TechNet Wiki” – The home of community-generated content about Microsoft technologies — that anyone can edit! Dive straight in! Use the search (above), tag cloud, featured articles page, or portals below to find the information you need. On any article, just click the Edit tab to add information — first you’ll need to Join and sign-in. See something we’re missing that you feel is important? Go ahead and create a page for it! “So what makes the TechNet Wiki so different? Well for starters it’s community driven, meaning that it’s not just a forum for a bunch of MS people to post docs in a one-way fashion, but it’s a way for you, the IT Pro, to post articles yourself. You can even comment and edit docs written by others, including yours truly,” note Microsoft. Here’re some thoughts from a couple of guys who’ve been deeply involved in the TechNet Wiki project.
