Some time before, I had a discussion with @Mico on changing the title of a question to be more useful. The general idea is to make it more useful for search engines. Since the question as was before was down-voted (and I can understand this) the new question is not a feature request but opinion on the suggested edits on the titles of questions.
Question (I will answer too):
Do we have to edit titles of users-questions? Anf if "yes" when do we have and what we have to keep in mind?
Old question (feature-request)
In the site there are many too specific posts and unrelated with the title of the question like this one: unuseful question-answer. I think that it would be a nice solution to add something like [TOOSPECIFIC] or [NOTREALLY] in their title, so that when someone have already used our community will know that the "google search" returned something not really useful. (This will give fewer clicks too and will not allow such questions-answers to take a high google rating).
Another solution would be to gather all these kinds of questions-answers in one topic with common newcomers mistakes or something like this.
