One-half of your nwk tumblr team is moderating a live chat during tonight’s GOP debate on CNBC. That means he’ll be approving comments and running polls while Howard Kurtz & Michelle Goldberg co-host a few hundred readers in a chat about 2012. Come, bring your armchair commentary! We want some of Tumblr Nation up in this business. The party starts at 8pm ET. You should be able to chat in the thingy above, but if not, visit the Beast. T-MINUS ONE HOUR.
