New kid on the block - Mixx to overthrow Digg?

After reading TechCrunch’s thoughts on unhappy Diggers leaving for Mixx, I tried it out myself - it’s definitely an improvement on Digg…  It’s got a much nicer look and feel to the site, it’s quicker, has a pictures section, and allows other users to tag and categorise existing stories. Overall - it seems much more usable than Digg, though it’s RSS feeds don’t seem as precise - not sure if you can have a custom feed of only stories that interest you, it seems that you have to have a feed of all of Tech, or all of Science, rather than a mixture of subcategories. Looking forward to getting to use the site more though!
