I actually wouldn't worry Janice, I'm still a newbie here, but I've browsed a lot and gotten heaps of info and answers, and at the end of the day, there are so many people who also come here for the same reason. I guess the thing is that so many people have come to know each other because they've been members/posting for a while, so naturally there will be tighter 'groups' even if they're not intentional. I don't know anyone here personally or at all but I don't have a problem with it since I only joined a few weeks ago, and I know that the more I participate, the more familiar I'll be around the place, and the moer familiar others will find me. It's a two-way thing, at the end of the day. I've personally had this kind of experience in another forum a few years back and seriously, at the end of the day, as long as it's providing great service and info to people, and as long as a large number of people are having fun here, seriously don't worry yourself. Just know that there are WAY more people who actually appreciate a go-to place like this and your blog than those who bitch.
And what's the bet that people bitching about this place actually visit it more often than not to look at info or look for answers to their MAC/makeup related questions, don't leave a mark then pretend they're too high and mighty and make rude comments like that elsewhere? It's immature, but just rise above it, knowing you've got a good thing going.
