GUIs: We decided early on not to create a GUI for MongoDB and let the community sort one out, which has had mixed consequences: there are now over a dozen to choose from! (We’re still hoping it’ll settle down.) 
This doesn’t apply to MongoDB consulting, but I’m not sure about hosting where 10gen is not yet present.
This blog is called myNoSQL and it is written by me, Alex Popescu, a software architect with a passion for open source and communities.
It records my readings, learnings, and opinions on NoSQL databases, polyglot persistence, and distributed systems -- subjects that I'm passionate about.
The opinions expressed here are my own, and no other party necessarily agrees with them.
If you feel I'm biased, I probably am.
