Judging by the quote-retweets, a lot of people think Twitter just announced you can only tweet 1500 times per month unless you pay $100/mo. (for all accounts, not automated)
To be fair, it's not like their messaging has been all that clear.
I've still no idea if/how my bots will be on Twitter in 4 days time. What does "a single authenticated user token" mean? One access token only per app? That'd be a bit of a bugger since my bots all share one app and I can't register any new ones because I'm not on the v2 API.
