>From my perspective you could contribute the most in setting up a
Hadoop + Mahout infrastructure and documenting the setup process and
the hello-world mapreduce program etc.  While we went through this
yesterday (thanks) I feel like people will actually get to DO the
things they learned later; so a written reference (new wiki page)
would be great, because these questions will be asked over and over.
Even better, and this is just an idea:  can we set up a shared AWS
account so each of us doesnt have to install everything by himself?  I
know there's the question of who pays for it, but that aside, are
there technical restrictions why we could not share an account?  One
approach would be each of us throws in $10, or perhaps theres a way to
split the bills between us according to usage, or, even better we
could push Noisebridge Inc to give us some allowance.  Getting a
turnkey cloud Mahout infrastructure for Noisebridge would be H-U-G-E,
even if it would not be ready in time for KDD submission.  Feel free
to take the lead on that initiative.  You would go down in the history
books of NB as a hero :-)

Erin and Mike are already working on transforming the data, so I think
we have already lots of manpower on that end.

Let's tentatively plan this Sunday night to get together again.  Erin
also mentioned she'd like to meet again before the next Wednesday.  I
can give an impromptu talk about classifiers/machine learning problem
Will confirm.
