Thanks Avinash

It's sad to see engineers ready to switch from one solution to another,
simply because they hear rumors about Facebook or some other large website
moving away from it. The part the really bothers me is how people were ready
to look for an alternative solution before they even verified this rumor or
even heard the reason behind the rumor.

I would love to hear more about data modeling with Cassandra. I have gather
a lot of good information from reading various presentations by Benjamin
Black, Jonathan Ellis and others. The most important piece of the puzzle is
to understand how you intend to access the data and then model everything
based upon that.

Cheers,
