I think this is a great idea for the community. I applaud this decision because there are quite a few accelerators, but the special part about YC is HN. Being open enough to give it it's own editorial steering wheel is a great indication of goodwill to the community :)
Now that HN is it's own thing, maybe we'll see access(api?) for vote attribution?
Is that even remotely possible? Or, are the implicit privacy issues too much of a burden?
