Here is a short list of blogs I have enjoyed reading. Who knows, you might enjoy them too!
WWdN: In Exile - If you haven't heard of this blog then you must have been living under a rock somewhere. If you only think of Will Wheaton as the guy who used to play Wesley Crusher then this might well broaden your outlook.
Blogger Tips and Tricks - As fine a collection of tips on how to squeeze the most out of Google's Blogger service as you are ever likely to find. Some of the tips may be useful for other blogging services too.
Your Neighorhood Reverend - One of the delights of Blog Catalog is finding blogs that are outside your usual frame of reference. Described as "the whimsical existence of a Memphian holy man" this is a well written and amusing blog, and certainly well worth the visit. I can only aspire to be able to write as well as he does.
MrCopilot - Mr Copilot is an embedded Linux software developer and consultant. Don't let that put you off, as there is some good writing here. If you are interested in messing around with Ubuntu (or Kubuntu for that matter) then you'll find some interesting anecdotes here.
LiveLife365 - Mike Foster's blog is great. Really, I mean it. Some excellent writing on a variety of subjects AND some of his own songs including the wonderful "I Miss My Hair" (which I'm considering adopting as my theme tune). Well worth taking the time to browse through.
