In “Twitter is really creepy” news, this happened. To be honest, I’m not sure how they get away with this. They’re not supposed to be allowed to pull from your web history or anything if you have the inferred identity and analytics permissions stuff turned off. My guess is that, like many things at Twitter, that feature is broken. Probably intentionally. And even if it wasn’t intentional, it’s not like they’d be willing to fix it: they don’t really have the manpower to do so.
Sigh. I hate that website.
