My partner in crime, Dave Bouwman, is currently running a survey called "What Do You Do? Geospatial Developer Survey" through May 9, 2008.  I took a look at some of the preliminary results this evening and found some very interesting responses (some good...some not so good).  Here the blurb on who should take this survey from Dave's blog:

Who should take the survey?

Anyone who writes any code that is geospatial in nature. From the Google Maps Mashup dudes, to those running some geoprocessing tasks with python. If you write code that has anything to do with a map, you're the perfect person to take the survey. Be sure to pass this url around to everyone you work with who is a geospatial developer - the more data points we get, the better. Who knows - we may even be able to influence the content at some conferences...

So, if you haven't had a chance to take this yet, it's worth the few minutes it'll take to complete it.  Here's the link (for copy pasting to all your developer buddies):
