Absolutely love this idea as I use many of the ones you mention to track my progress over time in addition to establishing a benchmark for my engagement. While approaching my year anniversary I have often thought of looking through the year and looking at the correlations between actions and SP gains. Unfortunately, it continues to be mostly due to buying Steem but I envision a future where I can see where my engagement has more impact for not only me but the ecosystem as well.

At some point it is going to have a self-fulfilling factor as having SP will attract a of of interest from users and various investors which means more growth and visibility.
Adding more small steps to reach along the way is likely to serve as reminders to people to tweak here and there. I think it would make a big difference overall.
