OT: Most active FLOSS project?

[Tshepang Lekhonkhobe]

Hello,
My curiosity says: which of FLOSS projects is the most active --
numerous patches? Is there any data out there that tries to
approximate this? Perhaps a among the tops is Linux, Mono, Wine,
mozilla-firefox, openoffice... who else? What about the most active
distros (perhaps a tougher one to anwer)? Thanks...
