It has it's advantages to be sure, I really like eventsourcing. For some kinds of projects it's the obvious way to go. Finance seems like a killer application, because of the way the entire audit trail is stored, and the system can often be rebuilt to a valid state upon finding and correcting a production bug.

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.
