In the video below, NY-based Tumblr founder David Karp provides an update on the micro-blog business. He explains that Tumblr is the easiest way to share anything online. He also describes how important the "reblog" concept is for Tumblr. Reblogging is where you share what someone else has posted on Tumblr to help it gain viral growth.

For some stats, David noted that Tumblr has 310,000 users (no word on active), 120,000 posts per day and they host 15,000 custom domains. The user number is up from 75,000 last October.
