Considering how fervently you all defend the creative efforts of the most lowly of flood fillers, so long as they're giving their stuff away for free, the continued digs at GoS (and its free creators, and its many pirate members) seem both petty and personal, though what GoS has done to earn the enmity of the PMBD regulars is not at all clear. There was a thread a short time ago discussing what sort of activities or behaviors were turning people off of PMBD and thus potentially hurting the pirate cause, and I'm pretty confident that disparaging a popular free site and, by association, its many CC creators, does not create a positive impression.
I don't see continued digs, there is a level of tension, but these discussions only get dramatic when goslings come and raise the level of importance. I like the creativity, the best finds, the theme threads, the request thread, lots of things at GOS. I usually have both GOS and PMBD open in tabs. I remember when the whole unfortunate conflict with Nouk arose, one of the first comments was "this isn't PMBD." It was a fair comment, because it isn't. It's also fair to say "this isn't GOS." Nobody disparaged the creators at GOS, no one ever has at PMBD. We're definitely on your side regarding the TSR creator is trying to pass off Corrine's mesh as hers. On the other hand, there have been extensive discussions about what goslings don't like about PMBD.
