It is far from perfect and the todo list is still long. You are, as it is a public repo, welcome to collaborate with us and make it even better. I can’t wait to see the first pull-request coming in!
You can also talk to us directly at Percona Live London where we will bring a revised version of our talk at Santa Clara. This time it will be aimed more at the practicality: It will contain less comparison with existing tools, be less theoretical and focus more on the how to do it.
A bit of a shame to do it this way: I tried several times to add the Spil Games Engineering feed to the Planet MySQL feed adder, but it fails on the feed validation and suggests to validate it via feedvalidator.org. However feedvalidator.org validates it perfectly fine as a RSS 2.0 feed. I did use the Planet MySQL feedback form twice but no reply on that and I think I will file a bug report later today.
