Which Frog is the big brother? Part 2

I took me mission to discover which is the older Frog brother of FaceBook and Twitter. I got one of each opinion on Facebook, and on Twitter Jamison Newlander replied (seriously!) but he doesn't know the answer.

I've always thought Edgar, but now I have this image in my head of Alan suddenly getting all protective big brother when something happens to Edgar. Fic may have to be written.


Look! Reply from Jamison! It's head Frog though, not lead, but close enough! ;)
