I tried to explain to the reporter why Cassandra's data model (particularly that it supports an arbitrary number of columns per row) makes it support denormalization better than traditional rdbmses, and somehow that got turned into "cassandra supports an arbitrary number of rows."
This and a few other poor explanations make me wince reading this. So I don't particularly recommend this article, although I've seen worse. :)

TFA does at least link the original interview w/ Ryan King of Twitter (http://nosql.mypopescu.com/post/407159447/cassandra-twitter-...) which is much better for people at HN level.
My own article at http://www.rackspacecloud.com/blog/2010/02/25/should-you-swi..., although high level, also has some useful links for those who want to drill down for more details.
