    Wiegley as maintainer was discussed in the gnu emacs dev mailing list for the past couple of months, hundreds of messages.

    John Wiegley is the author of eshell[see Emacs: eshell], a compiler engineer for like 20 years coding in C++, and is now a professional haskell programer. He lives in emacs.

    there is several video interviews of John Wiegley. http://pages.sachachua.com/emacs-chats/chat-john-wiegley.html John Wiegley – June 26, 2012 from Sacha Chua on Vimeo.

    John is a extreme emacs enthusiast, and his primary platform is Mac with strong desire to make emacs better on Mac too out of the box, and he is a very capable programer, and also a sociable person. I think John will bring a lot good things to emacs. Thanks John.
