Yeah, it is somewhat strange that Apache/IBM seems so focused on TDF/LibreOffice. And why focus on a somewhat hard to track (at least for a free software project) metric like downloads/users?
If you look at the communications from TDF/LibreOffice last month (http://blog.documentfoundation.org/) downloads and users estimates are only mentioned twice in passing. And Apache isn't even mentioned once.
I would happily read about Apache Office success stories and their development metrics if they publish them, but trying to compare them across such different project/communities seems doomed to fail.
I just tried to compare commits/developers between projects on ohloh. But even that is comparing apples to oranges, since LibreOffice only counts their core code/developers, while Apache includes even their website/marketing/wiki edits. Also LibreOffice is worth less because they removed so much dead code :) https://www.ohloh.net/p/compare?project_0=LibreOffice&...
