Are you a Django user? There’s an upcoming Django conference in Chicago in a few months, and I know they’re looking for speakers with MySQL experience in particular. One suggestion the organizers have floated is a talk on MySQL:
I’m looking for someone to give at least one MySQL talk there. In particular, I would love a (friendly but vigorous) “Why you should use MySQL instead of PostgreSQL talk”, as PostgreSQL tends to get a lot of love and attention at Django events, and MySQL not so much.
Take a look at it and see if you are interested. Presenting at a conference is one of the best things you can do for your career, your company, and your community of open-source software. I highly encourage it if you haven’t tried it.
