The problem with programming tutorials

I agree with the sentiments above, there's no clear policy other than this poorly thought out response by Jeff:

I think version specific tags, regardless of whether you're using new functionality or not should be added to a question. If a user is trying to solve a problem in C#2.0 style but you know (from the tags) they're using the 4.0 compiler then you can provide them with a 4.0 specific answer/solution which possibly is more succinct/better.
This also happened in the Sharepoint meta:

As someone who was a Sharepoint dev and admin, I found that to be a mistake and inconsistent with other dev sites in the SE network. Even the normally sane and rational Shog got this wrong too:

That said, some users just don't know any better when asking questions, some don't even know what version of the tools they're using, or how to find out.
