Forums remind me when I used to look for interesting things for me like Pottermore. As for a personal blog morphing into a blog, it can happen, there's the possibility but I guess it really depends on whether you have your goals and focus really clear and established and actually sticking to them. But either way, I think if the blog or forum has some refreshing and/or interesting topics and points of view, I'm on board. The thing is you really have to weed out the meh's from the oooh I'm on board.
