Sorry; I did look at the FAQ and search the archive, but still the answer wasn't clear to me....
So far I have an ordinary authorized Twitter web application using OAuth, not whitelisted or anything. From what I understand in the FAQ, that limits API requests from my website to 350/hr. People are meant to post tweets from my website. Does this mean that the total of all tweets through my website are limited to 350/hour? If users have to authenticate each tweet (which currently they do because I don't store the tokens), does this mean the the whole site is limited to a max of 175 tweets per hour total for all users? Sorry if it's an uninformed question. I did research it, & I've put in a lot of work to get the site to work; now I'm trying to figure out the policy issues....
