I think there's a lot of unintentional confusion going around between The Mall and The Treehouse.
The Treehouse is a place of discussion and conversation. Yes, The Treehouse can have some crazy and wild threads where the imagination is your only limitation when it comes to threads there - such as yes, dinosaur butts - but discussion does take place. The Treehouse, in a sense, is a forum for all topics that wouldn't generally fall under another PC forum. It is, though, a place of discussion no matter how wacky it can become. And even still, no matter where you go on PC, you'll always see "post-and-go'ers"; that's not the fault of The Treehouse specifically, but a site-wide problem that inevitably isn't going to be fixed in one fell swoop (as much as we might want it too.)
What people seem to gloss over in my opinion is the fact that no matter what forum we would have voted for - whether it was science, pets, etc. etc. - it would have taken away activity from The Treehouse. Maybe not in the overall scheme of things because that section will always be super active, but because we are creating forums that have not existed on the site before. As a result, threads that normally would have gone in The Treehouse are now going to different areas.
If you really think about it, The Mall when first created was set up to fail. Or rather, just have a lot of confusion centered around it (which is also evident by most of the posts.) No splash image, no concrete description, no clear...direction in lack of better words, as there wasn't a "leader" persay to point us in the right direction; the forum was left in our hands to direct it whatever way we want it to go. Which is why the pandomonium we've witnessed the first weeks is expected, and as Harley Quinn nicely pointed out, we're jumping the gun a little bit in terms of declaring whether The Mall is inevitably a success or a failure because no real concrete foundation was every created.
Right now, we have individuals stepping up and helping shape the forum into something unique and different than the other forums going on. The comparisons between The Mall and The Treehouse are unfair because in reality, every forum would have originated from The Treehouse if it didn't exist before the creation of The Treehouse. For instance, if Computers & Technology didn't exist but The Treehouse did, you'd see a lot of posts from C&T in TT. Arguments could be made that Roleplay Theatre could fall under Fan Fiction and Writing or Anime & Manga/Video Games could fall under General Entertainment. However, all of these subexamples have enough topic variability to exist as a separate entity; the same thing goes with The Mall with this direction of food, fitness, and fashion.
Yes, The Mall still needs some refining. We've made a good start so far, but there's still a lot of work that still needs to be done. However, with the right attitude and a good work ethic, we can most definitely shape it the way the community want it to look (: It's in our hands now and I know as a team we can get this thing to stay for good at the end of this trial period.
