Kudos go along with the blogs. It's just a way of saying you liked the blog post, without necessarily having to write a generic comment on how much you liked it (or perhaps to emphasize that comment).

At the end of a blog post, there should be a link that says "Add Comment." Underneath the text box, you can click to add 1 or 2 Kudos (in addition to the comment, if you wrote one), and then you just click "Post."

You can add Kudos to multiple entries; it's for each individual post.

its a way for jerks on your buddy list to be rude, when you write something from your heart they can rate it 1 kudo as opposed to 2 letting you know its okay but not good enough. this somehow makes them feel like they are nice its like when you leave the hairdresser a 50 cent tip when you coulda left her a couple bucks. 1 kudo is your oh so generous 50 cent tip.
