Oh, I tend to bite people when I find out they use another database . Maybe I should stop that?

You must be thrilled to learn that single server durability is coming. I look forward to a followup post extolling MongoDB’s virtues this fall.

Yes, it is a difficult, but not unsolvable, problem. Mongo’s made a bunch of tradeoffs in the awesome vs. easy to program area. For instance, remember last year when CouchDB was saying MongoDB sucked because of its lack of concurrency? That it was too complicated to do concurrency in C++ and that Erlang was the way? Well, now Mongo has concurrency, so on to the next “must have” thing.

People discuss everything from bugs to architecture to lunch on our various forums. I was trying to say, possibly badly, that we have a lot of ways for people with questions, problems, and suggestions to reach out.

Eliminating the methods I outlined, I’m not sure how people with suggestions could reach the developers, other than telepathy.

Also, the user you cite is far from typical. It sucks that some people don’t like Mongo, but there’s are a lot more out there from those who do: http://codeascraft.etsy.com/2010/07/03/mongodb-at-etsy-part-..., http://blog.eventbrite.com/guest-post-why-you-should-track-p..., http://blog.wordnik.com/what-has-technology-done-for-words-l..., http://www.engineyard.com/blog/2009/mongodb-a-light-in-the-d... and so on.
