I have come across this developer’s stuff a couple of times, but never really appreciated his contributions to the community. He has a plug-in called EngageBox that is so much fun to put on a site. Check it out here.

He also gives in depth process for Google’s Structured Data that is overwhelming at first but very informative. Check that out here.

I hope this helps someone else out there…
