Thanks for the comment! Honestly, I can't see it being sustainable in the long run. I think the reason that they are sustainable at the moment is because the platform is growing - when it reaches critical mass (I'm talking critical mass from a Metcalfe's law perspective) this will not be sustainable, but while I can use it I do, as I am not guaranteed upvotes - but once I build a solid following of upvotes or my posts get seen by enough people that I feel I'm helping the community enough, I will stop.

Thanks again for the comment!
