Last year, I was under the impression that Gather was a site for writers ready to post their work for critique, and polish their craft. I soon learned that it was nothing more than a "myspace gone bad" with flame wars, character assassinations against other members, circulating hate-list to new members via private email, false accounts created to slam other members, cliques campaigning behind the scenes to pump up ratings and votes for those in the circle, and bombarding "outsiders" with low ratings and harassing comments. Twenty word "articles" (many cut/pasted from Wikipedia or online newspapers with no sources sited) were posted to earn comments, which translated into points, which translated into gift cards or cash. I don't recommend anyone participate on the site, and would certainly be wary of entering into any agreement with Gather.com. Be afraid, be very afraid.
Besides, if you haven't spent the last year politicking on the site, building your "network", joining the appropriate cliques, and proclaiming your undying love to the ringmasters by faithfully offering lavish praise for their every misspelled and grammatically incorrect word, your work will be rated low and dismissed with negative comments. Or worse, ignored completely.
I'd rather get a legitimate agent rejection then go anywhere near that site again. I'm just glad I used a pseudonym there.
