It's been a while since I first came across www.Blurb.com. Then it was a blog "slurper", designed to turn blogs into books. Presumably the market for such a product was decidedly niche-like (too few really good blogs which could usefully move to the printed page, too complex a process perhaps for it to work well enough to convince the potential user); for in the meantime, it seems to have become a kind of jumped-up Quark designed to help turn any material into a professionally bound and dispatched volume for a mightily small price.
An excellent idea. So good, I might try it out this week.
If you're interested and would like to try it yourself, you can find out more here.
