A few weeks ago The Printed Blog surfaced as an aggregator of posts.
Unsurprisingly not far behind is the All Tweet Journal, published this week for the first time, featuring information gathered and submitted from Twitter.
The PDF download is only a page in its first week, but promises more. Given the amount of information --- links to longer text, photos and graphics --- it's hard to believe it won't be difficult to create a full-fledged publication online (and printable).
What isn't all that clear yet is what it wants to be. Its Edinburgh founders leave the door open to anything --- including frequency of publication and size, not just the content.
