this looks like a very shallow and weak defence of noSQL in reaction to recent attention to the fact that noSQL == noACID.
Lets see, from the article noSQL solutions are ACID if each transaction updates a single record, if you have sharding and no replication and if you have fsync turned on.
The default state of SQL servers - MySQL non-innodb aside - is reliable i.e. ACID. The default state of noSQL solutions is unreliable, and only Voldermort seems to go some way to addressing that.
Is voldermort the only reliable noSQL?
