I believe blogging is either for:
a.)people who just want to attention from random anonymous people with nothing better to do with the internet so that they'll feel appreciated
(consisting of 0.1% of the tumblr population)
b.) the random anonymous people with nothing better to do with the internet
(consisting of 99.9% of the tumblr population including me)
As a part of the latter, I shall help you waste time with all the cool/ silly/ funny/ interesting/ informative things I happen to reblog. Procrastinate and enjoy.
