There are other reasons to choose NoSQL For example, when Craigslist was using mySql and they had to change their schema, it took MONTHS to facilitate the change across all their slaves.

That isn't a reason to choose NoSQL. That's a reason to-

-doubt MySQL -- many of the purported downsides of SQL solutions (for instance the ridiculous "avoid joins" meme that has zero bearing on any good database product) are actually MySQL problems. Or rather, they were -- the product has made some pretty incredible strides.

-understand and embrace normalization. Most of the "we keep trying to change our schema and SQL is just so restrictive" stories could often be described as "the problems with denormalization".
