Twitter cuts its default rate limit from 350 to 175

this kind of thing is the reason you can't base a business off Twitter (and expect to sleep soundly at night).

make Twitter apps for fun. not for profit.

Making Twitter apps for profit is fine, just don't depend on it.

It is far better for twitter to rate limit the API to a level they can handle, than to get themselves into an unstable situation with fail-whales. The header says what the rate limit is so applications can adjust.

They're also limiting their own apps so it's fair.

I guess I don't understand why the default was set higher than they could handle in the first place.

Just like old times! :)
