In the past week, I've run across enough geo-tecky blogs that I set up a separate gadget on the side of this blog, just for this group. Here are the ones I know of so far. There are lots of pure tech blogs out there, these are integrate geoscience and the IT side. If you know of others, I'd love to hear about them.
Arrowsmith blog (Ramon Arrowsmith, ASU)
Geologic Froth: Digital Geoscience for Dummies (Kyle House, NBMG)
Open Source Paleontologist (Andy)
OpenTopography (GEON team, Chris Crosby)
Stratigraphy.net Internals (Robert Huber, Jens Klump)
