Why are TGPs better than picposts?

[SMG]

hm, actually picpost.com is now a really cheap galleryspots tgp ... I think I'm gonna use your test on a couple picposts ...

The reason I'm asking this is I'm gonna do something kinda different, but a lot like a picpost... its gonna be a picpost, but itll allow up to 5 pics instead of 3, and itll work like a toplist ... the more clicks that come in from a submitter, the more his galleries get pushed to the top of the list. It'll actually look a lot like a thumb tgp in the end, but it will have the toplist concept embedded, and will be a picpost in reality.
