Great explanation of Steemworld.org @brandonfrye.

It is a great tool that lets us know about the stats of an steemit account and I really appreciate the creator of this tool, that it enable everyone to check their Steemit account stats.

There is one more tool that I wanna recommend you to check it out. I think it is also cool!
