A lot of the people I know are from Age of Sail fandom, but outside of that, you might like cofax7 a lot for the link roundups, where I almost always find something interesting to look at or think about. tielan is a friend from Marvel fandom who posts about her writing and her quilting. And indiefic will have to grant you access to see stuff, but is posting regularly and you can get a sense of their stylings on their tumblr. Maybe you even know them already from Marvel fandom?
