Personally, I think reading feeds on a mobile device is useless, at least in my case there's too much information, and it needs processing, not just *looking at*.

To process my feeds I:
1) select feeds individually/category to make it easier &amp; faster to process the items based on keywords(mixing comics w/tech news would mix scopes)
2) if a title looks interesting: star it
3) further analysis of starred items

That said, sometimes I log in to GReader Mobile and filter a couple of items.
