That's how I started here. I set aside a couple of days and read every post here (it was a lot easier last year of course...this place is growing very fast).
It was actually a site review that made me realise that this was a place worth sticking around. Someone posted their new site for review. It was awful, and many members here gave a review, some of which were over a thousand words of analysis. And while that analysis probably broke the owner's heart, it was 99 percent true, wonderfully helpful if they took it, and the sort of expert view that is rare to find for free on a forum.
