So I don't interact with the community often - I find that the forums, for the most part, are people who are far younger than I am and often there's discomfort on both sides in regards to that. Because of that, I haven't noticed a lot of the issues that have been going on, and I'm happy to be in my own corner and use this site for what it was intended for - as a character repository site, where I can have fun and make my character's profiles look how I want them to, while occasionally playing a forum game here and there.
I think the main issue is that TH's community is trying to make it more than that. It's no longer just about the characters- there's threads for real life drama, politics, problems with artists, etc.; and I think a lot of that is what's really run down the quality of the site. However, compared to all the alternatives that have cropped up / tried to take off, I still like it here the best.
