Tumblr can be a very addictive site. It's a quasi-blogging platform, one that seems to fit between the brevity of Twitter, the social connections of Facebook, and the lengthy text posts of Blogger/WordPress. It's really great if you want visuals, music, or other media types.
Today, I'm featuring two sites that I follow on Tumblr. First, there's Comically Vintage, which features panels from old comics, usually with snarky commentary.
Then, there's Better Book Titles, where all kinds of books are retitled for comedic effect. This is an independent site that I happen to read on Tumblr. My recent favorites have been new titles for The Particular Sadness of Lemon Cake and Anna Karenina.
