It used to be -- and I used to use it frequently when it was -- the default site for finding WGs in the States. It was the go-to board for finding escorts while on business trips or at least certainly one of them. But the Craigslist Killer (Google it) put paid to that and the Adult Services section was shut down as a result. Now, Backpage (google Boston Backpage, Chicago Backpage or whatever) has taken up the slack. Basically, it'll be as reliable as any other classifieds site (Gumtree, VivaStreet). That means lots of dross and a few hidden gems.
