@matigo not too bad when you group like subjects in folders. I have all the youtube feeds in a folder, bloggers in another, artsy photo blogs in another. I don’t have any micro bloggers I follow (other than here) so I can’t say for certain how they’d fit but I don’t imagine it’s be much different if properly organized.
Heck, I could try it. Do folk here automagically get RSS feeds for their posts which I could plug in on newsblur?
