While some of what is posted is erroneous and/or sheer conjecture that is ultimately shown to be wrong, there is much accurate info here, stuff certainly NOT available from the WTS. Years ago there were some fine "heavy" posters here (Narkissos, slimboyfat, Leolia), and that sort of heavy, accurate research is no longer current here, though it's always available by searching since it's kept on the server.
committeechairman once said that he came here b/c official WT info is available here before the local elders get from "mother." So beside the shoulders to cry on, comrades to vent to, and so on, just from an info perspective, this site has great value.
