#2I'm very happy to see more OTP tutorials as of lately. I believe OTP can be one of the most powerful tools in an Erlanger's arsenal.

#3Those interested in this topic may find http://learnyousomeerlang.com/what-is-otp#the-common-process... of interest. It has similar aims but doesn't take detours for rebar, emacs and such (things you don't need for Erlang/OTP).

Stronger: If you are using Erlang for anything real and you aren't using OTP you are almost certainly doing it wrong.

Good point.
About the only thing I've found is the lack of pooling gen_server's built-in and limitations of using atoms for process registration as things I have design a solution for in OTP.
Otherwise, architecturally, I'm amazed at how much ground is already designed in OTP.

#6"OTP in Action" is an excellent book for learning OTP.
The following reading will take you a long way with Erlang:
Learn you some Erlang http://learnyousomeerlang.com/
OTP In Action http://www.amazon.com/Erlang-OTP-Action-Martin-Logan/dp/1933...
On Erlang, State and Crashes http://jlouisramblings.blogspot.com/2010/11/on-erlang-state-...
"Making reliable distributed systems in the presence of software errors" http://www.erlang.org/download/armstrong_thesis_2003.pdf
The last two links are "Erlang propaganda" describing the hows and whys of Erlang.

From R15B01 you can actually use "plugins" for process registering using the {via, Mod, Key} syntax.
Gproc supports this and using it you can do stuff like:
gen_server:start_link({via, gproc, {Your, "very", >, key}, [...])

OTP isn't just powerful, it's essential. You need to think in terms of what OTP provides you to program in Erlang effectively.

You can use Poolboy [https://github.com/devinus/poolboy] for pooling gen_server's.

#10I never understood why you have to take Erlang-the-language to get the distributed systems platform. It seems like the whole node management/serialization/"process" management and whatnot could apply to other languages and runtimes.
That way you could get Erlang's distributed platform, which is highly lauded, but mix it with a faster or more preferable language.
