I'm pretty happy with the RSS reader in the N900 (and 770+N8x0), it works pretty much ok and does what it's supposed to do.

A lot of non-fingerfriendlyness, no portrait mode, and does not really follow the windowing method used by for example the e-mail app.
I've been thinking about doing something about it for a while now and the CSSU work inspired me to take a look at it.
First was to get rotation and portrait mode working, that was pretty easy, pretty much a copy&paste job from my rotation code in Mapper.When rotated it hides useless functionality from the toolbar.
Next up is fixing the layout in portrait mode, as currently it sucks, as you can see below:
