A like button of sorts has been on my mind recently as well.
I created a page full of quotes (via Webflow!) and was thinking if my personal website ever becomes operational then it'd be cool to have a little counter next to each quote with a thumbs up (or like OP suggested, heart) allowing the visitors of my site to get involved.
Here's the page: not-another-universe.webflow.io/quotes
Also on a more advanced note (though not necessarily with this example), it'd be neat if we could organize the data ... so say on the side of the page or even placed somewhere else, wherever, a small box that shows the top 5 likes, dislikes, whatever's being tracked, number of times submit button has been hit, etc.
Thanks for listening.
