Twitter API, requests per hour limit?

Question

Twitter

Do I understand Twitter's restriction on the application correctly:
1. The restriction is imposed on the application, no matter how many users use it?
2. Sending a message + getting a result = 2 requests?
Is the 150 requests/hour limit only allowing 150 users to send 1 message per hour?

Answer 2

ugh, it's getting worse.
even when posting once a minute, the application will be suspended.
