Charity's talk about costs is annoying too. Honeycomb is the most expensive solution I've seen so far. Until they put a "we'll match your logging+metrics contact cost for same volume and features" guarantee on the pricing page, it's just empty talk.
Don't get me wrong, I love the Honeycomb service and what they're doing. I would love to use it. But this is just telling me "you're doing things wrong, you should do (things I'm already doing) using our system and save money (even though pricing page disagrees)".
