Twitter Reach Calculator

Given a twitter search query, calculates the a rough number representing the direct reach

Caveats

1. Doesn't take into account the fact that a given user may follow two people that tweet a URL ( e.g., just adds follower counts of all matching tweets )

2. Doesn't take into acount RTs ( e.g., if a tweet mentions the query parameter, and then is RT'd, the RT will not be counted )

3. Limited to first 100 results ( no paging )

Example Usage

$reach = new Twitter_Reach( 'http://ben.balter.com' );
