Choosing a database is a major decision for us (as with any young start-up). Once decided on, it will be hard to change the db both in terms of data migration and rewriting major chunks of code.

We’re taking into consideration ease-of-use, performance, scalability and price. The fact we’re using PHP is also a key player in the decision.

Please assist by commenting to this post about your db of choice. Bad-mouthing the other dbs will also help us decide.
