A thread can have a terrible topic but entail a worthwhile content
While some could have an attractive topic(that entices one to open them), but with terrible content
True, but a thread's title should give some indication as to whether you'd want to click on it or not. I fully agree that thread-starters ought to be required to change thread titles if they're extremely vague. I also find it annoying when a thread's title is something like "Hi" or "Bitcoin" (and I've seen threads with both titles recently). It's basic forum etiquette that not everyone seems to grasp, and I would support having some sort of rule.
However, given all the other problems this forum is facing and the lack of action on a lot of them, this is probably not something that's going to get Theymos's attention.
Edit:
Did you really have to quote the entire OP just to write your reply? That's another breach of etiquette a lot of members seem to perpetrate.
