TXTmob is a service, similar to electronic mailing lists and predecessor to Twitter, that lets users share mobile phone SMS text messages with both friends and total strangers.
Users can sign up to send and receive messages to and from various groups, which are organized around a range of different topics.
When an individual first attempts to join a private group, his or her membership will be listed as "pending."
Tad Hirsch, a researcher in the Massachusetts Institute of Technology's Smart Cities Group and Computing Culture Research Group,[1] continues to offer TXTmob cleaned up, packaged and released under the GPL via SourceForge.
Tad Hirsch, creator of TXTMob, was the subject of a subpoena by the City of New York in connection with several lawsuits against the City that allege police misconduct during the 2004 Republican National Convention.
