Sorry for all the typos. Was standing in a huge traffic jam, when writing the previous comment.
Also want to add another opinion. I was thinking about the two separate voting options, but I do think that this will not solve the problem. There are several reasons for this.

1. Steemians will be clever enough to find a solution to this problem by finding a new way to exploit it. It will not eliminate selfishness. People will just create voting groups. Where everybody is obliged to up-vote each other posts with 100%. Meaning that there will be no voting power left, to upvote posts which really deserves it, outside this ring.
2. It will increase the usage of voting bots. Besides giving your post some more exposure, it is a hidden way of self voting.

I don't consider myself selfish but I did upvote some of my own posts, luckily never a comment :).
In stead of doing this I'm now trying out voting bots, trying to give my posts some exposure. But I don't want to to this. But I feel that I have no choice cause a lots of us are doing this.
So after some thoughts, only popped up this morning in the traffic jam, I decided that from now on I will use the upvote bots only after the post is 12 hours old.
Why do you ask? There is a good reason for this but is a 2 side cutting knife.
I first want to have genuine upvotes and comments on my posts. So if I instantly use upvote bots, almost all the curation will go to these bots in stead of towards the people who really found my article worth an upvote.
But the problem is, that if a post is already has some value, other will be more interested by the post. Trying to get some curation or are thinking: hey some people found it worth to upvote, so it could be a great post.
This is the dilemma I'm facing at the moment.
(This time without typos, I hope)
