I'm an enforcer of the "comment kindly". Not only saying "Good post" but really taking the time to address the writer, letting them know what you feel about their post. Even if what you feel is 'generic', you can always broaden the subject to make some substantial comment, that the writer will appreciate more than just a cliché comment.

For example:
Did you like it? Tell them why you liked it.
Did they do something nice? Tell them what made it nice.
Did they use a good picture? Tell them why you think that.
Did they make you think outside the box? Tell them what you think now.
Did you feel compelled to write about something after reading it? Tell them.

There are so many ways to support an author. Your comment might be the one to make them feel appreciated enough not to quit. Why do I mention this? Most people quit Steemit out of two reasons: small return of investment, and no feeling of accomplishment. A comment might be the cheer they need to keep on being amazing.

And this is specially true in other communities... Now that I think about it, your pope is something we DO need in the Spanish community of Steemit. It's really getting out of hand over here hahaha
