I didn't really need a 'description' when I started - it was a Doctor Who tumblr.
Now, it's lots of things, I can't put a label on it. DW and other TV and films, landscapes, stars, the sea, pretty sparkly stuff, ghostly stuff, interesting buildings, quotes, funny things. And shoes.
And stuff I think some of my followers might like to see. I'm nice like that. Plenty of dinosaurs and Pokémon, but so far no naked men or dubstep. EDIT: that's since been remedied
I don't automatically follow back, I'll check out your tumblr first. If you post stuff I'm interested in then I'll follow.
