Is ideological segregation coming to our choice on where to live?

The Economist has a great article in this past issue about how more and more of us in the U.S. are living in “landslide counties” - local regions where political proclivities are pronounced and tend to vote consistently, and strongly, one way or the other. The reason? The article suggests people are choosing to move into neighborhoods where they feel their neighbors share the same values as they do.
Although this is not an entirely new phenomenon - there are conservative parts of the country, and liberal ones, the whole red state-blue state sort of explanation - this brings home the greater granularity with which this sort of division is shaping up to be.
I remember shortly after the 2004 election, Dan Savage wrote that this country is not composed of red states and blue ones, but rather an urban archipelago that is deeply blue, and a red suburban and rural America that is just as richly hued. In other words, urban Texas is more likely to vote Democratic than rural California. The map to the right describes the phenomenon well, and another (which I can’t find right now), shows the same map but distorted to reflect the relative size of voting populations (which demonstrates that red & blue are almost evenly matched).
I can’t argue with the logic, personally. I like living in cities, and have much more in common with people of different sexual orientation and ethnicity in cities, with respect to my values, ideas around leisure, entertainment and culture, than other gay white people living in rural and suburban areas (they do exist, but probably not as great in number). There’s something to be said for the ability to have a decent, respectable conversation with your neighbors about something deeper than the weather. In today’s volatile and sharply-partisan political climate, maybe that’s not possible in “mixed” neighborhoods.
As long as they don’t resort to insults or violence, I am perfectly content to share a block or even a building with people who share different values from my own (and I suspect that I already do, although I haven’t polled people in my apartment building).
The question that might come up, however, is if we are just setting ourselves up for stony silence and pent-up hostility, interrupted with the occasional flareup, between adjoining communities that used to intermingle and share resources. That scenario reminds me of what the Dutch called zuilen, a perverse form of which sprouted up in South Africa.

It’s the end of June, and I find myself mulling my next phone choices with a certain sense of anxious excitement. I currently have a Blackberry Pearl which I like pretty well (it’s certainly a lot lighter and smaller than my previous Treo 650, but I miss the touchscreen sometimes). Besides the rumors of an upcoming touchscreen-enabled Blackberry, there are two choices on the horizon: the Apple iPhone 3G and a Google Android-enabled smartphone.

The United States, until now maintaining observer status in the 2-year-old United Nations Human Rights Council (UNHRC; the successor to the UN Commission on Human Rights), 
I just noticed this past week that Google Docs (word processor, spreadsheet and now presentations, or, to use file extensions almost everyone knows now: doc, xls and ppt) now allows you to work on your docs offline - like if you’re on a plane or in the BART tube - and then synch up later when a connection becomes available (unfortunately, it hasn’t been rolled out to any of my accounts yet). Although Google Docs are still a bit clumsy, this is yet another step towards a serious step on Microsoft’s turf.
I’d like to point out an example of the sort of conversations that are happening across blogs that demonstrate the market, if you will, for dyalogues.
The United States is an institution that, like any institution can be condemned. If this country weren’t open to severe, biting criticism, it wouldn’t be the country that it is. Countries that forbid self-criticism either through law or officially-fomented nationalism are, well, not exactly the kinds of countries that inspire envy. (I’m thinking of North Korea, Iran, Cuba, etc.) Unsurprisingly, the U.S. has indeed survived Wright’s criticism, and doesn’t seem to have borne any permanent scars.
