(Especially new) users often use redundant tags in the title redundantly. In fact, by far the most common edit reason I use a the moment is “removed tag from title”. There’s a consensus that tags don’t belong in the title (see Using tags in question titles) – common sense also dictates this: in general, repeating tags in the title serves no purpose.
Is there a way of educating (new) users not to do this? For instance, could Stack Overflow not recognise when somebody starts or ends their title with “in X” (or worse, just plain “X”), where “X” is also used as a tag?
(And yes, I realise the irony of repeating two of my tags in the title – but the alternative title “Discourage use of in” simply didn’t have such a nice ring to it.)
Addendum: I’ve just found that Jeff Atwood explicitly encourages some of this use, e.g.
How do I tell what OS I am running on in Python?
… I actually disagree. Given that this question is tagged python, I fail to see what “… in Python” adds to the question title, and I think that Jeff’s answer isn’t thought through very well: his remaining points are decidedly dodgy, as has been pointed out in the comments.
