The initial reason for the tokens existence is for kick-starting the bid-based ad revenue sharing platform. If there are no bids for a given tag + filters, the popular page owner would show auto generated banners for promoted post instead. As no bids underly promoted, a daily mint of one STEEMSENSE could provide some form of reward despite of zero matching bids.
The idea is that next to STEEM, bids for ads can be made in STEEMSENSE as well.
There should be no peg, and I guess any airdrop would bring the price down. The first 10 STEEMSENSE are ment as an attempt to attract a bit of funding for the project, so I can spent some more time on it than the half a day per week I currently do.
If you buy some, DONT Buy them as investment. Buy them because you believe in the project and want me to speed up development by allocating more time!
If that part doesn't work out, no problem, things will just continue to move slowly and I'll just add that 10 STEEMSENSE to the airdrop.
