Twitter started here. The now defunct Dodgeball started here. This year, it's Shizzow's turn to debut at the South by Southwest Interactive Festival in Austin, Texas. Those of you lucky enough to be at SXSW this year will be among the first to use Shizzow, a location aware service based on the Twitter model. The API will be made publicly available, which will surely result in the development of popular tools. Obviously, privacy is a huge concern on location aware devices. Shizzow states they will require a wiretap (and not a regular warrant) to hand over a user's location.
