Yes! This is exactly what I tell new users who are disappointed that their blogs aren't making any rewards. So, I showed them how much they can make in commenting. Yes, most of the time it is not much, however, if they are in the right post it could possibly be very profitable.

I believe it should be community etiquette that bloggers upvote their comments. Numerous times I will look at the bloggers steemd.com page and see they have 100% in voting power, which tells me they are posting just to see what they make in reward. This community will be very rewarding to those who participate in blogging, commenting, and voting.

That's my rant. Some may disagree, but I'm just being honest with what I see.
