For anything that critically needs an audit log it's a pretty obvious choice (atleast compared to when people try to implement audit logs in a RDBMS).

I think it might also have a great deal of merit in prototyping applications quickly - Having the option to do just-in-time/memory projections while later switching to "real" storage seems really ideal to me if i'm just building something to validate it would like to defer those type of tech decisions.
