I saw that post the other day and gave you an upvote.
I'm just guessing here - but it may have not done as well simply because it's a lot simpler and most of those features already exist elsewhere. Right now (as far as I can tell) all that steemb.com does is:
- a little bit of global historical information on payouts (available on steemit)
- the top posts form the API (available on steemit)
- a page that shows a single user's earnings recently (available on steemwhales)
The post itself could have just been missed by many too, we all know there are some content discovery issues that happen from time to time. You could also open source it for extra credit, which would help others learn from your work :)
Thank you! I will add more useful feature to www.steemb.com
