This article is mostly marketing phrases from the websites of the various projects. Sadly, much of it is inaccurate, extremely skewed, or otherwise not useful for the stated purpose of comparing the listed databases.
For example, CouchDB having a "Main Point" of "DB consistency" might be the case, as it is for Redis, when there is no replication. In replicated configurations, it is definitely not true. Further, the MVCC is weaker in many ways than in a Dynamo system like Riak as you have no way to influence or discover consistency between replicas.
I'm sure folks expert in other systems can identify similar errors in the rest of the post. Can someone explain to me who the target audience is for all these NoSQL comparison articles? They are universally poor, yet universally popular.
