It’s Trent here from ActivePlace, what will be one day the worlds largest social marketplace in the health, wellness and fitness space. We chose MongoDB for a number of reasons, one of the big ones being scale as we grow and gather more and more data.
Anyway, good to meet you all and when you get a chance checkout us out and let me know if you have any feedback on what we’re building.
Hello @Trent, Welcome to the MongoDB Community forum!
Great to know you are a user of MongoDB. Yes, scaling with MongoDB is one of its better features. I come from a RDBMS/SQL (the other database) background and find MongoDB quite different - it is very flexible and easy to work with (as a developer). Nowadays I am honing my aggregation query skills.
You will find some useful resources here - at the top of the page there is a menu with documentation, blog posts, podcasts, etc., and of course you can always post a question and even post an answer a question. In addition you will find folks from all kinds of software background writing here and sometimes they have strange given badges like “database rebel” (I have one of those too 
). Hope you find all this useful in someway!
