In an unprecedented presidential move, President Obama has called upon people to start using a Twitter hashtag: MY2K, in regards to the fiscal cliff. The MY2K (as in “my 2k” – the extra $2,000 that would come from the current tax cut extension being proposed) campaign calls upon Twitter users (and has crossed over to Facebook) to tweet what they would do with an extra $2,000 and use the hashtag MY2K.
