In response to this query:

I get tweets like this:
http://api.twitter.com/1/statuses/show/28525953676218368.json
We're talking about a location search for St. Louis MO, radius of 30
miles. We're getting a guy from "Jeffersonian", but timezone is
Madrid.
Any ideas where this wire got crossed, when we can get it uncrossed,
or what the long-term viability of location based searches are?

I filed an issue last year and it was closed as fixed on January 8,
2011:
http://code.google.com/p/twitter-api/issues/detail?id=1348
I have a Perl script that will grab tweets in a 25 mile radius of
Portland, Oregon and dump them to CSV. I haven't run it in a while,
though, so I don't know if the results are better now than when I filed
it. If you have something to reproduce this, maybe you should re-open
issue 1348.
I guess given the low percentage of people who enter their actual
location in the profile, as opposed to being from "Botland" or "Earth"
or "Hilbert Space", maybe the Search API should only return geotagged
tweets when a geocode radius is specified, like the Streaming "filter"
API does. It's that or somehow "crowdsource" locations, which is going
to violate peoples' privacy if done without permission. To me it seems
like a tradeoff between clean but very sparse data or messy but copious
data that can be imputed or cleaned via crowdsourcing provided
permissions can be obtained. I can't put a business case forward for
either option from Twitter's perspective, but I think I'd prefer as a
researcher to have Search adopt the Streaming model and only return
geotagged tweets when a geocode parameter is specified.
