Tumblr!

I have one but I dont post, I only use it as a means of bookmarking my favourite posts porn

I just didnt want to be the first one in this thread to admit it.

I have one and I use it as the host of the blog for my website. It's also good for artist exposure and a good time killer.

I followed a bunch of educational/sciencey tumblrs the other day and so far I'm loving it. Somehow I feel like I'm using the internet the "right" way.

Almost went there once. But I'm a dude.

Aside from my personal tumblr I run one dedicated to posting hilarious screenshots from grand strategy games: http://believableworlds.tumblr.com/

It's somehow wound up with a buttload of followers and I get a lot of submissions and stuff. On the other hand it gets weird "neo-nationalist" followers sometimes

Video games porn? Aren't that what guys from video games forums are interested in?

I tried to make one but it tells me to sign up. I hate anything that involves sign up since 2013.
