"... Visual Basic.NET not backwards-compatible with VB 6.0. This was literally the first time in living memory that when you bought an upgrade to a Microsoft product, your old data (i.e. the code you had written in VB6) could not be imported perfectly and silently. It was the first time a Microsoft upgrade did not respect the work that users did using the previous version of a product." [2]
Personally I'd hate that stuff. Probably why most of the weekend languages are open source and can't be discontinued by some corporate overlord.

Also, amount of questions is not necessarily a good way of measuring a languages popularity. If a language is easy to use, it could have a large following, but not many questions. Hard to draw meaningful conclusions from the data posted imo.
If you are talking about Sharepoint specifically, then you should mention that in your post. Microsoft has a lot of products, just because one is losing popularity doesn't mean they have lost their focus.
