I recently discovered Jason Kottke via The Talkshow with John Gruber. In his most recent post about blogging:

A few weeks ago, I asked the readers of the Noticing newsletter to send in links to their blogs and newsletters (or to their favorite blogs and newsletters written by others). And boy, did they! I pared the submissions list down to a representative sample and sent it out as last week’s newsletter. - Jason Kottke

 

In his blog he links to a lot of interesting blogs, I recommend you to check these out.
