It's not ironic. Votes here are used to push the best content to the top. On Github you're not looking for the best content you're collaboratively building software so the tools should be designed to foster collaboration.

> On Github you're not looking for the best content

That seems like an odd assertion. Are you looking for the worst content then, or...? I can see an argument that voting would not highlight the best content, at least in some cases; I don't understand an argument that we aren't looking for the best content.

Conversely, HNews is intended as a constructive platform. Should the tools we use here not be designed to foster collaboration and constructive debate?

Disclaimer: I'm skeptical of voting both here and on Github. But I feel like the argument that the differences between the platforms are major and fundamental needs a lot more fleshing out.

Says the guy commenting on HackerNews, which also offers a downvote button. :)

There is nothing irony, you are saying people living in totalitarianism country can't fight for democracy.

We are not just using the system, we use the system here to improve the system itself that's why people call it constructive community.

Where's the irony?
