You could try "the list" on evolt.org (which site also has useful articles from time to time). It's somewhat web-centric, and sometimes seems plagued by HTML-slinging webmonkeys asking about which META tags will get their clients' site to #1 on google, but it also has some old-timers who know just about all there is to know about running an internet business. In any case, they're all professionals. The feel is somewhat similar, if a little less expert overall, to that of this site.
