I personally don't believe in the option to delete a post on here. I think it ruins the fact that Steemit is built into a blockchain.

The site makes it quite clear that tags are important, and that posts cannot be deleted, but in the event that you are unhappy with a post, you're free to edit/remove the content and perhaps replace that content before one full week has passed since the post was published.

I think the way it works now can enforce a higher standard of quality, given it promotes proofreading before hitting the post button.
