There are few extensions that used to work fine. But, since Twitter moved from 1.0 API to 1.1 API, it seems that all of them stopped working :(
Any help on this?
No, prpltwtr is not working anymore. That is one of those that used to work. Seems that Twitter cut-off many users with this new API :-(
Yep, the age of combining Twitter and apps like Pidgin is passed. The web is descending into darkness as APIs die and gardens are increasingly walled. Our only hope now is a hero...
Pidgin only supports Twitter with plugins. One I found is prpltwtr at http://code.google.com/p/prpltwtr/ As Twitter has been waging war on third party clients there may be issues but from what I have read it sounds like it still works for now. There is also the plugin pidgin-twitterstatus at http://code.google.com/p/pidgin-twitterstatus/ which could be handy in some cases though not exactly what you are looking for. Everything else I am finding dates back to 2008 or 2009. At least these two projects are still active to some degree. Good luck.
