It is a shame. TweeGo is probably the best looking and most native Maemo Twitter client. Very smooth scrolling (unlike Khweeteur) and intuitive UI. However the lack of feature implementation let it down badly.

I would like to see auto refresh, portrait mode, DMs, @mentions and picture uploads.

Is it open source? I seem to recall it being written in C. would be good if some Devs could contact the original coder and maybe collaborate on the project to get it finished.

Its a very highly polished program and would be a shame to let it fall by the wayside.
