I'm going to guess you come from the ops world, I suspect most dev's using mongo aren't really deeply knowledgeable about the things you point out. Sure you know what replication is, but its different once you actually configure it and are tasked to maintain it.
We've been using Mongo in production since 1.6, and I can say I've encountered a lot of things you described in your original pastebin. I'll say it, the product is crap. I've spent more sleepless nights working on mongo than I have with anything else.
This site a scam? Create a fake account using a completely random name, it seems to have found a lot about "shpadoinkle Hassenpheffer" on the internet, I however can't find a single reference to the name...
