I use reBlog as by [tag]RSS reader[/tag]. There aren’t too many sites I keep track of, only like 20-25. I like it because it’s set up on bastone.org, so I don’t have to worry about something going wrong with the other sites out there, like Bloglines or Netvibes.
One of the functions you can is publish items that interest you to a blog. I’ve done just that, publishing the articles I like here. I’ve also played around with the WordPress plugin, and the layout is a bit clunky. That blog is here.
Do you use an RSS reader? If so, what do you use?
