My Identicon looks like four shurikens with big arrows pointing at them as if to say, "This dude's Identicon has shurikens in it. SHURIKENS."

comment List of desktop GIS FOSS case studies
When you're asking a question where the collection of answers is the answer (here, all the various case studies) you should make it community wiki. Each case study should get its own answer, and then people can vote them up or down based on how interesting/useful that particular study is.

People always say that, but I wonder: steep relative to what?

comment Define “geospatial data” for a non-GIS professional
Sorry - I intended that the counties/populations list would be implicitly located within a state and country. Heh - you can tell I'm in local gov't.

comment How to represent bimodal attribute value distributions on a map
The transparency lets you see the actual density of lines - more lines make for more opaque color. Basically, it just prevents the mass of green lines from turning the whole segment into a solid green bar. It's a little weird in this application because the overlap of the lines is caused by random jittering, rather than actual overplotting (compare with this scatterplot:had.co.nz/stat405/resources/drills/plot-drills/ggplots/…).

I think the first idea is brilliant, but I'm having a tough time visualizing the second turning out as anything but grey goop. Do you know of an example?

comment Buffers of public transportation transit times
I actually did something similar a few years ago using some arcane ArcGIS tool. The difficulty here is that public transit times in a city with three tiers of bus service and light rail are unlikely to be linear with distance. The nice thing about hooking into Google Maps is that it does a good job of picking optimal routes from A to B for me.

Could you elaborate a little more on what we'll see if we click that link? I'm a human, I don't like parsing URLs :p

Thanks - hadn't even heard about that.

This is how I feel about the situation. This is not how my employer feels about the situation. To give the benefit of the doubt, if you get a list of addresses from a recognizable IP address, it's not that much of a stretch to imagine that someone could figure out what the addresses relate to.
