The only effect it might have to slightly alter the overall bias of the site. Which is not necessarily a bad thing.

HN already has something of a negative bias towards the work of the various security services (that is, the mood is largely pro-Snowden and anti-NSA) - having a better balance of views may well be a positive effect.

Similarly for the pro-capitalist bias here, and what almost amounts to a religious veneration for VCs and the very wealthy. Then again, HN is a bit of a chimera in the topics it covers. So we do have some diversity of interests and opinions.
