Instead of enabling commenting on your blog, you can let readers ‘react’ by marking the post as ‘funny’, ‘interesting’, or ‘cool’. So far I’ve only seen this on one Blogspot blog, Galway Library’s blog.
If you know whether there’s a plugin doing this, or if it’s a general (optional) Blogspot feature, please let me know in the comments.

Don’t know, but that’s pretty neat.
