And so far I really like it! I know there are a lot of people out there who are all, "Well wtf is a TUMBLR!?" and actually I rarely use it...but the nice thing about it is that you can connect all (or most) of your social apps together! Meaning if you post something on twitter/facebook/wordpress/what have you, tumblr posts it on your tumblr blog and distributes it to whatever else you want it to go to.
