I've been playing around with open source twitter clones, and I said to myself:  Self:  Twitter for bears/cubs/chubs and admirers would be awful neat. 

I'd do it just for fun, so no revenue stream.  There'd be no tech support, obviously.  It would either work or it wouldn't.  I'd probably write a python client to make it easier to use, when I get the time.

Would anyone be interested in such a beast?  Or are there too many twitter clones already?
