As it stands, I don't see how this manages to improve upon the basic blog (which is Hackday). Upvotes are not really worth it there, because Github has Stars. Meaning that your upvotes are less valuable than a Star on github. Stars translate into other non-tangible benefits, like better chance of getting a job.

I dont know how you could create more value to hackers. Fact is, we are a hard group to deal with.

I'd have to agree with this one. Though I like these kinds of hack aggregators, I think yours missing some kind of fundamental product. A favorite of mine is codepen.io – the hacks are organized in a similar fashion but you have the advantage of building natively, forking, and creating collections.

I find the idea of using your engine as a aggregator for github very interesting though. I am not familiar with the github star and watcher apis but there might be a way to push upvotes/favorites/likes to github through interaction on hacksy, though you would still face the battle of bring users over.
