It took me a long time to 'get' tumblr'. I pumped my twitter feed in, my disqus, my friendfeed, rooted around a bit and left it spewing out content all over the net for ages and then one day, it fell into place. The thing about tumblr I find most fun is there are no instructions, so there's no rule book, which kind of makes it the best place to learn the etiquette, ways of interacting with people and just generally enjoying the whole make your own coffee book while hitting the dopamine pellet release button in the brain for hours on end (I'm not alone being a serious junkie for tumblr). I do whole nights sometimes and suddenly feel like hitting the sack just around the time when I should be getting up. But that's OK. I value my beauty sleep ha ha.
You can add me if you wish, or check out some of the new kids on the block like 9GAG, vi.sualize.us or even, if you were paying attention to that digital social networks visual I posted earlier get into the original tumblr - Deviant art.
