It's hard to tell how much Jimbo's to blame for the state Wikipedia's in, but from what I can tell Sanger at least partially holds him responsible. Either way at this point I think Wikipedia's too far gone to ever really be fixed in terms of its overwhelming and thoroughly anti-intellectual political bias and agenda-pushing. Too many admins who are too heavily entrenched and an executive who at best doesn't care and at worst encourages it. There've been a few decent alternatives that've come up but Wikipedia's a de facto monopoly on internet info, same as Google. Nothing could truly replace it, and nothing short of a complete administrative purge and management reorganization could fix its problems.
