I didn't see any good solid reason in that link, did you?
I don't see there, how redirecting to Q&A is better in any way. For example, can you tell me where are my posts now?
Where is, for example C# in Turkish? Looks like they are gone with the wind now. If you would link back to an MSDN site, then how come that doc is explaining what they are doing? It says, migration was completed, really? Where?
