I use steem.supply a lot.
I find it one of the most useful tools on steem.
For those who are concerned about their monetary well being here on steem or the success of their blog, this tool can give you a lot of insight to the "health" of your "success".

Let's run through the screens

This first part is where you can find out how well your blog is doing. Just put in your user name and it will give you these details.
On the left you can see your voting power and how much your vote is worth.
You can also look up any other user.

If you notice, this is my blog. You can see it has an overall value of $391. I have $22 of potential rewards, which is just the stuff I haven't received yet. And my potential growth is 5.72% as of right now.
Underneath you will see Liquid and Invested
Look underneath and you will see the authors ( you) potential payout in SBD (Liquid) and Steem Power (Invested).

Moving Down The Page

This gives you a visual of your revenue stream.
The Pie chart is interesting. It is the ratio of your posts to your comments. Don't overlook this information as commenting itself can be beneficial. But, please. No copy pasta, okay?

The chart below tells you how much your posts have made and when they are going to be transferred to your wallet.

Content Insights

This is straight forward and useful information.

Notice the average revenue per comment.
There are steemians that do nothing but comment and do well, bless their souls!

Social Insights

This chart tells you how many upsteemers (resteemed your article) verses people following you.
As you can see by my chart, many following, few actively or 0.0186393% I think this is to be expected. If I ask myself why it may be something simple such as the time of the week and time of day I post or, God forbid, I stink! Haha!

Followers

I find this one useful. These are the people that contributed to your success. Don't forget them. I always upvote their comments as a way of saying Thanks Everybody!

You can also go to their blog and resteem and comment back by clicking on the users. (I right click an open in another tab.)
