It's now possible to create a PDF ebook out of your LiveJournal and DeadJournal blog entires. Check out the service at LJBook.com. Once you've produced your PDF ebook, you can use Lulu.com or another POD firm (see list of such firms at http://www.bookmarket.com/ondemand.html) to produce printed books one at a time.
Now where is the service that will do the same for these blogspot.com blogs? I can't wait to see one develop.
