I think this is going to be a steadily-growing problem for SO. I already discount old answers of "Not supported, try this framework" because they're often about features which arrived in a later version. Eventually an awful lot of replies are going to be offering deprecated methods or unnecessary workarounds, and I haven't seen a good plan for maintaining quality as that happens.

Yes, especially web front end development. I still get hits from as far back as 2008. I do do a quick read though because some of the experts are decent enough to point out the changes for the current time, either as an update to the answer or a comment.
