I think a LOT of people are gonna be thinking the same thing... "Her?"
Regardless, Hermes was what I used when JB first came out and although I use Waninkoko now, I'd personally like to thank Hermes for the hard work and effort.
But it's sad to see him go. Hermes probably can't find much of a challenge? The PS3 is already fully opened up. Now it's just up to the community devs to customize and release more homebrew and make the various exploits user-friendly.
