That does seem to depend on why/how it ends up at Apache. Something like OpenOffice, or the myriad of Java projects, which have just been throw in under the umbrella is more or less abandoned. There seems to be some misconception that Apache has a number of developers sitting ready, or a ton of money to hire developers to take on any random project.

Projects under Apache really only works when the developers are involved and follow the project. At this point I'm a little unsure what The Apache Foundation provides, beyond hosting and some legal support.
