I have now installed the Openheart protocol to my blog, which means you can click the little heart emoji and it will make me happy. (Nothing else.)
Huge thanks to Tracy for her step-by-step tutorial, I only had to find where to put the code snippet in my theme (which is very different from hers) but everything else was incredibly simple!
Every time I see someone do this I get a little closer to adding it myself. Nice work!
