Should You UPVOTE Your Own Post?

I know the facebook algorithm punishes you for liking your own post. They see it as desperate and deceitful when trying to make your post look more engaging.

However, on steemit there is an "Upvote post" check box option when posting.

It seems like they're trying to make it more convenient for you to upvote your own post.

So...what are the pros and cons of upvoting your own post here on steemit?

Thanks!
