Is it selfish to upvote your own comments?

Some thoughts about self-voting comments that I just had and wanted to share

I was just writing a comment under a post and after I finished writing it - I upvoted it.

And then I asked myself the question:

Why did I upvote it? Is it selfish?

Many people have the believe that self-voting is a no-no and I understand that.

Upvoting should be a tool to curate good content and with it create a proof of brain which decides which content is good.

But voting is also a way to use ones own stake and investment in STEEM - STEEMPOWER - and to use it - how one thinks is right.

And especially for comments - I often spend quite a lot of time writing it and I do believe that they have value. And I want them to be seen.

So that's why I upvote them - I don't want them to go under in the sheer amount of comments.

What are your thoughts about this? Do you think steemians deserve to use their STEEMPOWER (investment in STEEM) to give themselves a visibility push or should we only hope about getting discovered by other steemians?
