Do you mean boring and bad? I might be conflating them a bit, but the local breweries are definitely mostly bad, not boring. Linden Street is mostly boring, as is Drake's, but I'll take them over the bad ones any day, obviously. (I also have no idea what the deal with Linden Street is, since the Dock seems to have taken over their entire brewery.)
Anyway, it depends on what establishment you're talking about. It's actively detrimental if one of the three taps at a local place is Line 51 because their beer is awful. Even places that have 10 or more taps can frequently be filled with absolute garbage out here, only salvaged by something like Death and Taxes, which obviously anyone in the bay can serve. Places clearly want to serve Oakland beer, but this means Line 51 and Ale Industries (and to a lesser extent Drake's), so it's not like there are options around. That's what I mean by slim pickings, I've found myself in situations where I would expect to be able to find something interesting on tap, only to be disappointed, alarmingly frequently for how good the beer scene is supposed to be over here.
