Well written article. I think most people who do not have a background in data are unaware of the various options out there and fall for the marketing behind hadoop like tools.

I would urge people doing analytics to take a look at kdb+ from kx. Unless you have ridiculously large amounts of data(> 200 TB), I can bet that you would be better off with kdb. The only downside is that it costs a lot of money which is a pity.
