Most every time I see a request thread, it is usually closed with a statement such as:
"I only want it because of the community, I would be a great addition etc. etc. etc."
The truth is there are very few trackers with communities like the ones you would expect. Now keep in mind, I'm not flaming any "top tier" trackers, but there are certain ones that are most certainly overhyped and misconstrued in a way that misrepresents the actual community there. In fact, the communities at What.cd and Waffles have some of the most fantastic communities I have ever come across; in terms of music lovers, you have every type of person imaginable. You can get recommendations about the newest and oldest music, from contemporary jazz to noise, and everything in between.
On a specific "top level" site that I have seen people requesting because of the "community", I have found the forums and people to be cold and alienating. In fact, this is true (for me) for more than one case. Most of the most requested trackers have boring and irksome forums.
The fact of the matter is you can never know what the community is like until you are a member there. You may have that person who praises the community there, but more often then not it has been hyped into something that is bound to disappoint.
In closing, I have found that SCC has the most comprehensive selection of content anyone could ever ask for. It has all the new ScT releases, TL and FTN releases, with great packs as well. All these people who want that "Level 10" (note the quotations) tracker for the community seem to be putting on a visage to pretend like that is what they want out of a tracker.
But hey, that's just me.
