Thread display and navigation seems to be the challenge on a small screen.

Why? Usenet news works *very* well in an 80 column text window so I
really can't see why a very similar text interface shouldn't work on a

Hmmm, that is one answer ... Tin etc could work in a terminal emulator,
but it would need a virtual keyboard added for navigation keys losing
screen estate.

Compared with the rest of the phone/tablet GUI, and modern desktop
applications, this would seem a bit archaic, and chase them in the
direction of Google Groups.

Some users could be forgiving though ...
