I really enjoy Tumblr. Probably not Tumblr culture, but I follow those who have similar tastes. I really like the ability to keep a digital scrapbook of things I find visually appealing and the fact that others might find delight in it.
Pinterest, though, I cannot stand. Don't ask me why - my vocabulary crumbles into a series of grunts and rambling.
I'll come back an edit this post to include some of my favourite Tumblogs later tonight when I'm home.
I love it. I check my personal tumblr account everyday just as much as ffffound. I also used it to built our band website, just to simplify things. People can follow us, and all the posts we make will stream through to facebook and twitter. Makes life a lot easier.
I'm a big fan of the way this person sticks to a specific theme within their posts. I love that you can get an idea of their mood or theme for the day according to their posts.
I think that's what the excellent blogger's/ tumblr'ers (?) do:
They have a cohesive sense of narrative. I hate blogs/ tumblrs that are disjointed and don't have a clear idea in terms of what they are trying to say.
