I think of all the presents I got this year, my favorite is the Amazon book review Ben Collins-Sussman wrote for Practical Subversion.
When I originally started work on the book my intention was to take a different approach from the existing Subversion documentation, targetting a more experienced user as opposed to the newbie. I figured that since the existing documentation was already there filling the newbie role, there would be room for a book that didn't spend a ton of time teaching the basics of version control, and just jumped right to the stuff you need to know to really get going with Subversion
According to Ben's review I appear to have succeeded.
I've seen a number of reviews of the book so far, and I've enjoyed reading all of them, but I think this one is my favorite, both because it tells me that I accomplished my original goal and because it's always great to hear that people you respect like your work.
Thanks Ben!
