I managed to sign all the keys from DebConf14 within a month after the
conference ended, but I had still a pile of keys to sign
going back to DebConf11 from several minidebconfs and other small events. Today it was frakking cold and I finally managed to sign something close to 100 keys. I didn't sign any key with less than 2048 bits, expired or revoked.
If you got your key signed by me (or get it in the next hours), sorry it took so long!
