Twitter is the latest piece in one's digital identity. Where I am, what am I doing, at this micro moment, is for me to advertise, to make public. What's public is no longer private (duh), and thus, is up for grabs for everybody.

As Justice Harlan wrote more than forty years ago, "(...) a man's home, is, for most purposes, a place where he expects privacy, but objects, activities, or staements that he exposes to the "plain view" of outsiders are not 'protected" because no intention to keep them to himself has been exhibited. On the other hand, conversations in the open would not be protected agaisnt being overheard, for the expectation of privacy under the circumstances would be unreasonable."

Twitter users may save lives, but more often than not, Twitter does not serve as as back up 911 number. It is a way to keep in touch it is a way to be tracked down. The line is, indeed, fine. As always in digital privacy issues, it is the aggregation of data that is the threat. Now that Google may buy Twitter, there is a real possibilities that our sweets little tweets may be exactly located on Earth, courtesy of Google's Latitude.
