There is only one RSS reader you'll ever need as mentioned it is Viigo and it is available in project Tango beta and it runs perfectly well on the Bold!
I'm running version 2.2.82 and it runs perfectly, brilliantly, addictively well. I swear I consume posts quicker on it than on PC. Can't live without it now I reckon.
Viigo is a solid app (at least on my pitty little 8100), but it really needs to get the functionality to sync with Google Reader. Right now it will sync your feeds, meaning that you can set it so that all of the feeds you have in Google Reader show in Viigo. However, that is really pretty useless, since it doesn't sync the read/unread and starred/unstarred, etc. If they add that functionality this will be the best RSS app by far.
