Is it possible to use Twitter's advanced search function (or something else) to find people that tweet about a certain topic regularly, or that match a certain criteria?
For example, I'm looking for people who play soccer-baseball (also known as kickball) in my area and have a lot of followers (lets say over 5000).
The only thing I can think of is to perform an advanced twitter search, and then "study" the search results for profiles that meet my criteria.
Is there a better way?
