You have too much free time on your hands! :)
I'd suggest a script that calculates the amount of locked Steem in inactive accounts (say, unused for the last six months). You'll be quite surprised and then probably shocked, when you realize what will happen to the already falling price of Steem if every one of these accounts decides to cash out :)
Locked Steem can also be used as a metric for Steemit popularity and possible future price volatility of the currency - the higher the price of Steem, the more likely people would return to Steemit to cash out.
