I had the pleasure of being invited to give a quick introduction to the Heartbeat API at WordCamp Seattle!
Thanks to the organizers for the opportunity, and everyone who showed up to listen to me speak very rapidly about polling awesomeness.
As of WordPress 3.9, the heartbeat api is no longer experimental. Use it in your plugins, but only in the admin. – @GetSource #wcsea

You can download the slides in PDF, and see the slides inline from Speaker Deck after the break.
This is just an introduction — For a deeper dive, check out this talk that was done in a longer form, and has example code attached.
If you have any questions, comment here, and I’ll happily update the post with further info!
