Hello to Thursday - Community Win,
for todays "Community win", I decided to pick the topic "ease of use".
One of the strong points going for the TechNet Wiki is that it is pretty accessible and easy to use. All you need to get going is a free Live-Account (technically for reading the Wiki you don't need an account, but for pure win I am sure you want to comment on the content you liked :)). With the account you can log in and start to contribute your experience and know-how by either adding articles ("Post an article" in the upper right) or editing existing ones (either navigate to an article via the portals or search for one). Both adding and editing happens in an editior within your browser, so you don't have any added requirements. Actually, for a detailed guide and much more pointers, there exists a wiki article here already.
So where is the win in it? The win is that its not an complicated platform for an exclusive group of people but everyone interested can participate without meeting many requirements. 3,379 users already decided to contribute, join the crowd!
