I'm thinking that it might be a good idea to add a feature in Twitmonger for us users to set a maximum limit for content in buffers (E.G. 2000 tweets max in home).
Alternatively, you could force Twitmonger to clear all data but Followers' Analysis upon startup. This should greatly reduce clutter, old tweets no one needs anymore, etc.
Just think of the joys sighted people have with no slow clogged computers taken over by Twitter clients. I personally am requesting this option to be user customizeable, only to hopefully... Lower the number of upset people who want old tweets to stick around forever.
Followers' Analysis shouldn't go away, however. I really like it.
