I agree, the advertising on FT seems to get more obtrusive all the time (or maybe I just notice it more when I'm on a slow connection) and its tendency to lock up IE if I touch the keyboard while a page is loading (on those days when FT is up) make another forum appealing.
Of course it's not the forum provider (FT or errorplan) that makes these discussions valuable, it's the co-conspira... fellow posters. If the FT regulars start posting on EP as well (or instead), it would quickly have value.
And if the EP forums evaporate one night, we'll all just move somewhere else, right?
