AnnMarie Walsh found a home by tweeting about her homelessness. She also was featured in a teaser for a documentary about Twitter and traveled to Los Angeles for a speaking gig at the “140 Characters Conference” focused on Twitter.

Walsh told the Daily Herald, a suburban Chicago newspaper, that she has recruited other homeless people to Twitter. “Twitter is our community. Anytime something comes up, you can tweet. There’s always somebody there.” Daniel Morales, a homeless man in New York, reunited with his daughter thanks to Twitter.
