Hello,
3 cents from a perspective of someone who did a lot of searching of quality
3rd-party Erlang software during last two years, for the purposes of r&d
first and later for the production use in a startup.

Centralized repository is tempting (I missed it at the beginning), but it
also requires lots of Q&A work. It can be obvious for anybody who
participated in maintaining some Linux of *BSD distribution. Also it can
reveal specific social incompatibilies between users, as they needs vary
more than most of people would like to admit. And it's not very good for the
perception of the community to start a centralized service which will fail
later.

The simpler step is to make searching easier. A website aggregating some
automatically-retrieved info (from googlecode, github, sourceforge) with a
human-entered content (by those  authors who'd like to care about it) comes
to mind. The results could be sorted somehow, with a raw google search
output as a last resort. Something like that could be plugged into Planet
Erlang.

There's no silver bullet when it comes to managing external software. In
production you usually want to stick with carefully chosen and often patched
specific versions of 3rd party stuff, otherwise you easily introduce a new
point of failure and make the release management pain in the ass. I'm very
happy that  Erlang is the first language making a sane conenction between
HA-world, where you think about your production environment in a very
specific way, and the usual "opensource libraries for all, let's grab it"
approach.

cheers,

-- Wojtek
