Today I and Paolo registered at TechEd 2007 and used our first day to do book shopping. We've finally seen a pile of our books Introducing Microsoft LINQ on the shelve and we hope they will sold out within Friday! We also made the new DevLeap site live - it has an english version now (it was only in Italian until yesterday).
We will be around in these days, if you want to meet us feel free to contact at info@introducinglinq.com.
