This looks neat! I keep a similar list for conferences focused on web operations. All the data is in a YAML file, and it's four lines of ruby (excluding the template) to generate the site.

We published a huge list of conferences at http://techconfs.co. List has not been updated yet for 2016 dates, but maybe you can find some new conferences of interest on the site.

Nice idea. I've wanted something like this before when I was looking for cool conferences to attend. I added OSCON to it.
