How to Analyze Twitter Followers

[Klarke]

I'm working on an infographic and I need a way to analyse the followers of about 25 to 50 industry twitter accounts to figure what type of people their followers are.

twittersheep.com used to do exactly this, look at the profile description area of twitter and produce a tag cloud of a given twitter account's followers based on terms from their profile fields.  But they are no longer online.

Anyone know of another service that does this ?  Or can think of another way to get this data.
