with the exception of a few things here and there, birdman doesnt really "release" stuff. really he from a fascinate perspective he:
1. first integrated bln into kernels, and all kernels built since then have come from that jt/birdman build
2. got a lot of the aosp stuff working, which going forward is really important (he and jt were all aosp pretty much by themselves)
3. has a .35 kernel booting, and is working on (may have done it already) upgrading out bootloaer to accept it and boot android
is he going to be the guy releasing a ton of roms/kernels/mods? no...are he and jt ultimately responsible for all the major things done for aosp/gb etc...yes
hes more of a big ticket guy...hes always working on stuff in the background
