what does 'listed' mean on twitter??:S?

[wittytoad584]

lists are a bit like groups on Facebook. it's nothing that important, people just like having more lists 'cause it's a bigger number and you know... people like big numbers :L because I'm a belieber, potterhead, killjoy and parawhore, people might add me to lists called 'I Love Bieber', 'Potterheads', 'MCRmy' or 'Paramore holics!' or something. hope this helps at least a bit ;}
