Fair enough, I can understand that viewpoint. However I do think that separate forums can be created with similar appearances, but over time evolve to have entirely different communities and cultures. I've seen this happen with godlikeproductions.com who split their userbase in half in to two websites for a year or so. Initially the two were "the same" but after a year they had developed very different cultures and focuses. So even just the saidit software with another name at another url, giving it another focus, is enough to attract some users. Although advertising forums is hard these days, so you need some sort of "hook" to draw people in if you're looking for good growth. Anyways, that's my 2 cents.
