Wikisimpsons - The Simpsons Wiki
Twitter is a social networking website.
Homer Simpson didn't know what Twitter was and had no desire to find out, but he wanted Bart Simpson to tweet about everything he did. Krusty mentioned Twitter when he was told everyone looked things up on Wikipedia when they didn't understand his references. Jonathan Frink mentioned that Bart tweeted about Homer's bed wetting problems then Krusty re-tweeted it. When Homer started to look for a missing Bart at Moe's Tavern, he told Marge to tweet him if he turns up.
