Blogs at Penn State Community

I am working with a faculty member who is having students use blogs - she is following their postings with an RSS feeder - We started with google reader, but it wasn't reliable or timely for following comments - then I tried My Yahoo - better - but didn't get everything - following both entries and comments...

Last choice was Bloglines - and so far, for entries, it seems to be working fine... Haven't tried to follow comments yet that way. Does anyone know why one would work better than another - or if there is a preferred RSS reader for PSU Blogs? - Are there plans for an integrated PSU feeder tool at some point?
Thanks!
