MongoDB 2.0 Released

I think I speak for everybody here when I say that 1.8 + 0.2 = 1.10.

I'm interested in learning more about MongoDB so that I can use it for web apps. But some comments I've heard about it(especially here <a href="https://plus.google.com/111091089527727420853/posts/WQYLkopE813" rel="nofollow">https://plus.google.com/111091089527727420853/posts/WQYLkopE...</a>) seemed to discourage its use. Can someone explain to me why it is "criticized by academics"? And what its pros/cons are?

I have no idea how anyone who's ever read the mongodb source code can entrust it with their data.

A few months ago, I saw an online interactive 'trainer' of sorts for MongoDB, much like Codecademy's JS tutorials. Does anyone know what I'm talking about?<p>EDIT: Damn Google, you good: <a href="http://www.mongly.com/" rel="nofollow">http://www.mongly.com/</a>

A bump like that should be for backward incompatible changes but it actually looks like a makeover to appeal more to serious biz customers that would have trouble getting on to a 1.0 technology.

I'm curious as to why MongoDB is so popular. I chose Riak, and my purpose here isn't to bash Mongo, but to understand what was the key feature that made you choose it?<p>Is it pure speed on a single machine? Is it the query interface? Something else? Datacenter awareness? Geographic support?<p>The key features that made me choose riak: - built in distribution/clustering with homogenous nodes - bitcask had the level of reliability/design that I was looking for. - better impedance match for what I was doing than CouchDB (which was what I looked at before choosing riak, but couch does view generation when data is added and I need to be able to do it more dynamically.)<p>What sold you on Mongo? What would you most like to improve?<p>(Please don't let this be a debate, I'm more interested in understanding the NoSQL market, what other developers priorities are, etc.)
