Is that long line on Halloween leading to house that gives out full-size candy bars? Nope, it’s the crowd clamoring for Twitter lists, the hottest topic this week in our Twitter recap. As these lists move out of beta into the mainstweam, everyone’s finding it’s a great way to organize your friends and to find new folks to follow. Services like Listorious.com offer a handy list of lists organized by topic.

As you get into the spirit of All Hallow’s Eve with a gallery of Twitter pumpkins, here are some things to do on Twitter when you’re dead. Speaking of dead things, is privacy’s demise the fault of Twitter or because kids took over Twitter?
