What other things would you like to be able to do with your Gridcoins?
Gridcoin network is designed around the flow of gridcoins in exchange of computer power.
I see communities surrounding several coins donating to charities and trying to get adopted by shops. Shop adoptions have usually little success due to very low user base of the coin, high price volatility doesn't help either, but it's only a secondary cause.
I think we should only focus on development and quality of the software and build a platform for commercial projects. This way gridcoin's hardware network will grow and adoption will grow, shops etc. will come on their own if gridcoins will have an intrinsic value.
Short answer: I wish it would be possible to exchange gridcoins for computing power of my desktop.
