You've got the traffic you'd need to advertise a book. Future blogs can be written in word then pasted into the blog prog to avoid having to strip them out later. There's plenty of printers/publishers doing small print runs. Try the family history ads. Beware of Publish On Demand/POD deals that sound great. Most of the rip-off merchants operate there apparently. Dunno about prices up there by I'm guestimating you'd lose 1,000 - 2,000 pounds if you didn't sell any copies.
