Shortly noticed: André's website now supports some IndieWeb features also. This post serves as testing its WebMention feature (so you can see it in action as well ;-))

I am relying as him on IndieWebify.me for checking the markup, since Yandex Webmaster Tools require a login as of lately.

Yes, Google has a Structured Data Testing Tool but its crap. It will rather detect schema.org markup then microformats (since they have a stake in the former).

If you want to debug Microformats, take a look at the OpenLink Structured Data Sniffer extension as well. It feels a bit yanky, but does its job quite well.

When will you join the IndieWeb movement?
