Too many people start a new thread instead of replying to a thread
Too many people start a new thread instead of replying to a thread. There are many ways to solve this, but this needs to be improved.
Merge new comment into an existing thread.
This is probably the easiest fix. And each time you move someone's new message to a thread reply you teach them to do it better next time! So this solves both problems.
Modify UI design to make it slightly more difficult to start a new thread vs reply to an existing one.
Any other creative idea.
Bottom line, look how many requests are solutions to this one problem. Add those votes up!
