Create link to page on home page to talks/demos/etc

[kevin-postman]

Frank recently spoke at APIDays and Eric Wilde has had a post or two as well. It would be good to have easy access to these sorts of details about Workflows for anyone joining or coming in later that wants to learn more about workflows, who is talking about it, who is using it, etc.

This would be a separate page with a link possibly near the top so it's pretty quick/easy to find on the main page.
