I actually agree with the OP in general. I have a mistrust of MongoDB overall, and avoid using it in big, data-intensive situations... BUT, in LocomotiveCMS and a few others, it make brilliant sense. Like you mentioned, it's very lightweight in terms of DB-writes, and allows for a flexibility that when put together the way the the Locomotive team has done makes a CMS a wonderful thing for end users. So I think you guys are both right in the this case. Choose the right tool for the job and all that... and the Locomotive team definitely chose the right tool.
