The largest boon's to the currency right now I believe would be:
More Exchanges (bleutrade c-cex, poloniex, cryptsy, bter, btcchina?)
A built in marketplace into genius. Allow simple, cost effective listings, perhaps an integration of open bazaar?

Beyond this I would like to this coin live up to its name and do something novel in the crypto world.
Currently there are a few problems which are plaguing every coin, adoption, identity, and longevity. People are typically interested in crypto, but lack proper information/experience to really 'jump in' The more genius removes friction from that entry point the better off it will be in the long run.
So partnering with places like gyft, shapeshit, and other instant coin services will bring some good exposure, but I believe a strong roadmap that alters the PoS implentation a bit to pave the way for future adopters to get involved typically I believe this has to run in conjuction with a Proof of Age and Proof of Quality. Together those 3 systems can be algorithmic-ally entwined to provide no only distribution and adoption solutions, but also eliminate scaling problems by properly incentivizing nodes big and small.

A developer/bounty fund would probably go a long way as well to further involve the community. Perhaps a fund funded by a few masternodes?

Just some initial thoughts, most crypto is simply cloning old ideas with new graphics I hope genius is different!
