RSS stands for Really Simple Syndication, and it's a great way to catch up on all your favorite websites at once, especially those that don't update that often.
I use newsblur.com, but there are many others, like Feedly, etc.
You can add a feed to a newsreader site (like newsblur) by copying the link on the little orange RSS icon that's now at the top of the blog.
EDIT: Edit: After some crazy testing with the W3C validator and lots of bugfixing, the feed now passes W3C as a valid feed! I tested the feed on NewsBlur and it seems to work fine, although an earlier bug with dates is still there (probably a caching issue though-- after a bit of time hopefully that fixes itself) And I should also update all the [ tags ] to do proper formatting and things, as right now it just shows all the codes as is, which is less than optimal.
So this feature is not QUITE finished yet. I'll update this message when it's ready.
