TT via API


Hi there,

I was wondering if tweets that are sent via API are eligible for Trending Topics list.
Imagine I have a microsite which you could sign in with Twitter.
After you sign in, you see a text box.
You type in your tweet and click submit.
At that moment, a designated hashtag is inserted in your tweet and the tweet is published on your Twitter account with that hashtag.
I wonder if enough people does that (within a certain amount of time obiviously) the hashtag will be on Trending Topic list.
Or are the tweets via API not eligible for TT list altogether?
