More time wasting!

Hi, I've made a tumblr: http://alekschang.tumblr.com/

I like to share music and movie trailers and such, so I figured it could be cool. Problem being, I'm not sure how to get comments on tumblr posts, so that aspect sucks. How else am I supposed to know that the four of you out there are reading my posts? =[

Any ideas on whether I should move to tumblr or use both tumblr and blogspot, or just forget this whole tumblr thing to begin with and stick to my old ways? For the time being, please check it out!
