Yes, thank you. Details about the trade-offs involved would be better. My objection is that collectively dealing with them as "the NoSQL databases" tends to obscure that e.g. the key/value stores have very different design and performance trade-offs than CouchDB does, for example. Redis runs entirely in memory, which has big implications for both speed and data set size. And so on. I should have said "trade-offs" to begin with...that was the heart of what I was getting at when I said "strengths".
