I was playing with search macros in live.com and was amazed at what we can do with those. In past I could not search for keywords only in MSDN forums specific to VSTS. If I did a search in web, then my results had non-forum stuff as well, which was a clutter. Now I created a search macro to do exactly that http://microsoftgadgets.com/forums/7153/ShowPost.aspx . The macro is shared, so just add "macro:naren.vsts" at end of keywords in live.com search and the results are scoped to only VSTS forums. It is possible because of macros functinality in live.com and meta tags in forums.
I can also do complex queries like "show me all unanswered questions in WorkItemTracking forum" and also add it live.com as an RSS feed to check unanswered questions whenever I go to live home page! Doing queries like getting all questions answered by me is trivial. I have a tool now that will show me results of keywords from VSTS forums, msdn (by appending site:msdn.microsoft.com at end of query), both search.msn.com & google in separate windows - comes handy when searching for an answer.
