ok, it's day 18 of the post a blog every day challenge and I am stretching I know, but perhaps some of you will find these feeds/blogs as entertaining as I do:

• popehat - http://www.popehat.com/feed - a blog done by some very articulate lawyers. I like how they manage to explain things so non legal eagles can understand. I also tend to agree with them on free speech issues and the like. Their posts are usually entertaining and enlightening.
• bad astronomy - http://www.slate.com/blogs/bad_astronomy.fulltext.all.10.rss/ - Contrary to it's name, this is GOOD astronomy. Lots of nice discussion about current events in astronomy and explaining how things work. It's really quite fascinating.
• Russel Corkers blog - http://etbe.coker.com.au/feed/ - In particular his 'interesting links for the month' have resulted in some great videos or things I would otherwise have missed.
• Linux Weekly News - http://lwn.net/headlines/newrss - Not just weekly, but daily feed of happenings in the Linux world. If you aren't a subscriber, go and subscribe now!
• National Geographic Found Photos - http://natgeofound.tumblr.com/rss/ - A mix of photos from the National Geographic Society. Sometimes there's some quite striking ones that come accross the feed. Many from long years past, black and white, color, everything.

There's more, but I will leave it at those. Hope some folks find them interesting...
