Erlang expert help Erlang - 14 years experience

Coming from the Erlang background, I found some interesting applications for Go's capabilities and developed a number of self-contained applications at different levels of maturity. While I still dislike a few things about Go (nothing is perfect!) it is a great tool for many problems.
