I've been happily aggregating away today, and it really works! It cut down my news reading time dramatically. I may have to buy this program. What's better is that I feel totally up to date - I know immediately when things are updated, so I don't need to be contstantly watching or bouncing around to different sites.
Now I just need to get more efficient at the 18,754 other stupid time wasting things I do every day, and I'll be all set.
