Well, we never can hide our roots ;-)

Logback has been developed by the same guy who wrote log4j 1.x. He left and log4j 1 was not maintained a long time. But before a good while a few others have teamed up to bring the project back to life. With log4j 2 we have looked closely at other frameworks, including logback, and tried to make things better. Actually we have found a few things which we consider better. Still you need to consider log4j 2.0 is a young framework and in beta. That said, we are always glad about feedback. You and your developers are invited to join us on our mailing list and tell us what you think - good or bad. Thanks again for your interest (and bearing with my english)
