At least once a day, I see a question titled with something along the lines of:
dynamical systems question
where the first part of the title is also a tag of the question. These question titles do not provide any information that cannot be found in the tags and thus are maximally useless. From another point of view, such a title would be equally (badly) fitting to every single question in said tag. I propose that such titles are blocked automatically, i.e., the asker cannot post the question and is shown a notice urging them to choose a better title.
Barring punctuation and grammatical number, the title is one of:
[buzzword] [preposition] [tag]
- tag is a tag applied to the question or a synonym thereof
- buzzword is question, issue, problem, …
- preposition is about, on, with …
A much stricter version of this filter (banning question and problem from titles altogether) exists on Stack Overflow, Super User and Server Fault. This is not what I propose here. In contrast to these filters, I cannot imagine a false positive for this filter, i.e., a good title that would be blocked.
I am aware that some stubborn idiot will find a way around this filter – they are not my target group. My target group are askers who see the error of their ways and change their title to something more informative. Going by this post, such askers do exist.
