I've been on TVtropes a long time. I was introduced to the site in 2007. I usually avoided the forums, but any time I got annoyed with the direction the site was going in I'd try to find discussions about it on other websites. So I am aware of many of the things that the site is mocked for, like Troper Tales.
Speaking as someone who's diagnosed with Asperger Syndrome, and is sometimes guilty of overthinking things or getting worked up about stupid shit, the habits of autistic individuals are the bane of many wikis. They are more likely to remember minor details that can flesh out an article, but many wikis end up devolving into lists of the most trivial things, usually written by people who take the subject too seriously and don't get that sometimes, fiction is unrealistic. The problem is when other people aren't willing to point out to them when they're putting too much importance on something, and that's something that's affected TVtropes.
Fast Eddie was a horrible administrator, and his inconsistent approach to the site's issues have tainted it for all time. Apparently, it's okay to be a creepy bastard on the forums, but it's not okay to call people out for being creepy bastards. And his crusade against negativity, despite the fact that he was usually an asshole to anyone who challenged him. I was angry when certain tropes were split off into YMMV pages, but in retrospect, it's not a bad idea. I think the problem is is that it wasn't done for the sake of reducing flame wars, but because he hated negativity. It's true, the site did use to be too vitriolic. But the mods seem to just hate negativity in general, regardless of whether its well argued or not. I guess doing the right thing for the wrong reasons was a pretty big part of how Eddie ran the site. Like only removing a lot of creepy sexual stuff when it threatened the site's ad revenue. I was hoping the change in site owners would stop that trend, but the recent removal of Wallbangers proved me wrong. I admit I enjoy reading a lot of the negative tropes. Wallbangers and DMOS do have a lot of stupid examples, but a lot of the time they actually do rip apart things in a story that actually deserve it. Wallbangers also wasn't just negativity, it actually served a purpose. I think people are less likely to add that stuff to the regular pages if they have a place to vent. It's also against the rules to link to the pages, so I don't see how the fact that the pages existed was hurting anything.
"Throwing the baby out with the bathwater" is a phrase I've often found myself thinking of when it comes to TVtropes. There's a lot of stuff that was beyond saving, and deserved to be removed. But there's also been a lot of stuff that was fine, but just needed to be monitored a little more closely than a normal page. But TVtropes has always been more likely to just remove things rather than actually try to fix them. For example, there's a page called Fallen Creator, detailing creators who fell from grace because the quality of their work declined. M. Night Shyamalan, for example. While that sounds like a magnet for bitching, most of the examples were very informative, and usually didn't display any unnecessary hate for the target. Sure, a few creators were added whose works are still getting critical acclaim, but most of the page was fine. But being a negative trope, it was still moved to the Darth Wiki, and then locked. I'm amazed that they made a thread solely devoted to discussing if characters qualify as Complete Monsters, given how little work most editors are willing to do in making sure tropes are used properly.
I think one of TVtrope's biggest problems is that the users are often more concerned with creating new pages instead of improving the ones they already have. Stuff like the Useful Notes pages can be interesting, but I've always wondered if it's really something that should be on the site. And of course, there's the obsession with creating every conceivable variation of a trope. No one will ever say "No, that's too minor to have a page". And the site's grown so damn big, that enforcing any kind of quality control is like ice skating uphill.
There have been a few improvements over the years. Entries starting with "This troper" are almost totally gone, a lot of natter has been cut and trope entries are much less likely to look like message board discussions. But a lot of fundamental problems remain, and probably always will. I was happy to hear that Fast Eddie had sold the site, but I wasn't sure if the new owner was actually going to try to fix the site, or just keep the status quo. I'm not surprised to hear that he really hasn't done much besides redesigns. Oh well. At least we got strike throughs back.
I probably shouldn't complain too much. Truthfully, everyone has their own ideas on how the site should be run. As many problems as I've had with it over the years, I don't necessarily agree with everything critics say about it. I believe it's the Enyclopedia Dramitica article about the page that says that it's a clusterfuck of a bunch of competing philosophies, with everyone editing the site based on what they think it should be.
