Quoting John Kalucki <j...@twitter.com>:
Just as all other track parameters, you'll receive all updates up to a
certain proportion of all statuses -- then you'll be periodically limited,
denoted by limit messages.
The proportion is pretty generous. I don't think there are enough Geo tweets
in the whole system to get limited, never mind within a few bounding boxes.
Yeah, I've so far collected a total of 300 geotagged tweets
"overnight" for PDX, out of many thousands from our "active night owl"
tweeters. ;-) Even on "track", I rarely see limit messages. A "track"
filter for "sea,world,killer,whale,orca,shamu" the other day only gave
me one limit message with four dropped tweets, for example, and that
was right after I started the test.
