I'm sitting in the state of the ASF session at ApacheCon, and Noel Bergman is giving us the facts about the ASF incubator.

• There now 33 projects in the Incubator
• 23 of them have graduated
• 4 are "retired", they didn't make it
• The Incubator PMC is the second largest in the ASF, with 47 members, and more pending

The incubation process is explained on the incubator website.
