Interesting. I found Twitter to be vastly better than other social media companies. Far better documentation (though weird complicated auth where I get 4 pieces of info for some reason). Far more stable and understandable. Twitter returns a ton of data in each response so there's no need to go making multiple requests.

Compare to FB which is just a nightmare of trying to guess and figure things out. It's so bad. If it reflects their underlying model at all, their main codebase must be very difficult to work on.

Charging is a welcome improvement over the previous situation: Deal with Gnip or other data brokers. They're "Enterprise". Get no information, have to deal with a long sales cycle and sales team, have to wade through tons of BS to figure out what you need. It sucks.
