Thanks for reading and sorry for the late reply. I've been so busy and not getting notified for older posts. I think there is much value in watching your growth rate. It can also help us learn how to grow faster by doing what works and not doing what doesn't as much. I use a spreadsheet in my phone for basic tracking. There's also some tools you can use that make certain charts for you. I've yet to discover them all but there's 2 repositories I like most: steem tools and steem projects. They have lots of tools in there to get charts.
SMT's might be groundbreaking. I really look forward to how they'll be used.
