Is Groovy a lost cause? Things to watch for open source project managers

While I’m not a user of it yet in any real sense, I can say with confidence that I expect Groovy to grow and become a stable platform. The ideas and people behind it are terrific. However, there appears to be some problems with the project as it attempts to get over the hump. There are potential lessons here for open source project mangagers. I hope people share how they get past this point.
