I’ve followed Jon Udell’s work for a long time. I’ve found him to have some of the most interesting, original, and clearly presented thoughts on information technology over the years. I’m giving him a blog shoutout because recently he’s been delving into topics near and dear to my own heart. Namely geo web services, exploratory spatial data analysis, urban planning, and GeoRSS. If you’re like me, you’ll want to check out his blog. Especially these entries:

• What’s easy, and what’s hard, about getting from Excel to a GeoRSS-enabled mashup
• A geographic analysis of local crime data
• Excel geocoding adventures
