There are positives and negatives to both sides of the issue.
I'd like to have control over my threads. Especially if I create a thread that is asking a question, I get my question answered, then I delete it. Or if I made a mistake, things could be fixed or edited.
-The edit feature would be really nice, I see countless threads every single day with mistakes, and the first post in the thread has nothing to do with the thread, just calling out the mistake was made. People imbed videos incorrectly all day long as well.
I guess most of the negatives deal with irresponsible people making stupid threads and then deleting them quickly.
When I think about it, there could have been legendary threads that didn't exist, because they could have been deleted previously.
But I don't agree that when some 12 y/o kid posts something really dumb, and then people start ripping the shit out of him, and he cant delete it after he realizes he made a mistake.
