Ceki is not liking the Apache model. He left because of that. You can read more about his reasons on his blog: http://ceki.blogspot.de/2010/05/committocracy-as-alternative-for.html http://ceki.blogspot.de/2010/05/committocracy-as-alternative... But still he is a community member and PMC of Apache Logging: http://people.apache.org/committers-by-project.html#logging-pmc http://people.apache.org/committers-by-project.html#logging-... On the other hand, we (the Apache guys) are not liking how the logback project is operating. At least it is me who does not like it, but I guess the others think similar. We want a community driven logging project which uses the Apache License. We surely don't want a logging project which is officially run by a company (like QOS runs logback). I have seen many cases where this does lead into problems. That said it will be difficult to motivate Ceki to get back to Apache Logging. But we are open to his contributions and hope that there will be a good, technical exchange between both projects. Another personal note: I am really against person cult. The Apache Logging project has some really great and experienced committers on board. One of them is working on Java logging for around 20 years and he set a very, very high bar for log4j. Having Ceki on-board is definitely of interest, but he is not the only person who knows about logging. Please have also in mind, that a new log4j2 release is just the beginning of our journey (hopefully).
