I would pay personally to keep it ad-free PROVIDING it didn’t start to suck in other ways. (Eg I wouldn’t pay for facebook because it sucks overall, not just because the ads suck. I cannot define what makes it suck – possibly just its ubiquity and the ever-youtubier free-for-all on non-friend pages.)

I know that it’s crucial to my place of work, and in the same way we pay for hootsuite or whatever tool we’re currently using, we’d pay a decent retainer for better analytics and back-end things. Whether we’d pay for ads is something else; the twitter audience would react badly to that I think.
