Self-publishing services that promise to print your tweets are hardly new — 140bio, twitprint, tweetbookz, and many others have been down this path before. Newcomer Scribr goes a bit further by adding Twitter, Tumblr, Facebook, Flickr, and Foursquare to the mix, which can be collated and printed out in a $45 pulp-and-print book. It's similar to a printed version of your Facebook Timeline. Scribr isn't just lazy journaling; the service can email you writing prompts nightly, and your responses will be added added to the rest of your digital ephemera. Co-founder Adam Henson told All Things D, "We want it to be as easy as possible for the masses to do this, because most people just aren’t good at taking the time to write a journal." If the web collapses, you'll want to preserve those humblebrags in print, right? Sign up for at Scribr; invites should go out by the end of January.
