Our SOA Compass book is still going strong after one year on bn.com and on Amazon. It changes places sometimes when new books come out, or with events, but I'm just glad to see it in the top ten for SOA books. It's been a year to this month that the book went out and we've had quite a few comments, reviews, and questions about it over the year. . In that time, the number of SOA books out there are rapidly climbing and as this technology (or is it business?) evolves, I'm sure even more will emerge.
