Pros: Very easy management, consumption, sharing of feeds and articles
*no vote on service/support because I haven't yet experienced it, not because it's horrendous
I use Viigo exclusively to consume news and feeds. It's very easy to add new channels and manage them. I highly recommend this. Some of my feeds include huffingtonpost, reuters, cnn, BBC, brandcurve, and startup spark.
It definitely saves me a lot of time since I can compartmentalize my time so that I only spend time reading my feeds when I can't be doing anything else.
I read it when I'm tired and lying in bed, using the john, in the subway/bus (content is downloaded to the blackberry so you can read without service connection), waiting in line, walking home...
