I just started using this google feature, and it's awesome.
There are a lot of websites out there that I check regularly...and some of them only get updated every week or so. Instead of checking back every now and then (or continually) all I do is put the all these website on google reader, and when I go to google reader it tells me what websites have been updated, and lets me read the content right there.
The only negative aspect is that if I want to leave a comment, I have to leave google reader and go to the actual website to do so.
In any case, a really cool feature.
Thanks, Aaron J., for telling me about it.
The rest of you should check it out (and if you don't have a google/gmail account yet, consider switching over).
