I've been looking around the community and there are whole conversation threads where nobody has liked any of each others comments.
If somebody says something to you, like it! If someone makes a post, like it! If you make a post/comment, like it (it won't give you points, but it helps grow this by going up in discovery ranking)! In my community, I don't have a single post or comment that I have not liked.
Let's bring the same energy here!
