I'm using tweepy to access statuses/filter. Having standard access, I can stream 200 users in my site follow list. I'd like to stream the 200 most active users and pick up the rest with scheduled API calls.
I thought I would simply calculate the number of statuses posted during the last month for all users in the follow list. I don't know of any way to accomplish that. I was thinking about retrieving the the status ID from exactly one month ago, but I can't trust my cached statuses to represent the absolute beginning of the month. Also, the cache is cleared when I modify my strategy for dealing with timelines and such. I am currently following 100 users so this isn't a problem yet. I use PHP and MySQL... and a little python.
