Sometimes there will be spam but since people have started leaving really (and I mean really really) long and meaningful comments, I consider myself blessed. A lot of the comments under my posts are longer than some posts on steemit. :) This makes me incredibly happy and I definitely do not mind when someone comments without an upvote. It is not that I do not like money, I DO, and it does give great pleasure to see my post-payout good, the number of upvotes is a good thing too. For example, I have a post with 83 upvotes so far and 15 comments that are just incredible and even though the pay-out says only $2.21 my heart is in the right place.

We need both, emotional support, and the financial support that you mentioned, but since we are emotional beings, I just need to say that I do appreciate an upvote WITH a comment more than just an upvote :)
