I'm all in favor of letting people work from home and facilitating remote work for certain kinds of projects, but if you seriously think remote work is no less collaborative or technology can replace "face time", I assume you're missing
a lot of human communication skills.
Not only does physical interaction have a much higher bandwidth, it goes well beyond just the work. The more you interact, at lunch or in the hallways, the better you will be able to communicate with each other on all levels, and the better you'll be able to collaborate. And this is not a one time thing, this is a continuous process.
I would never hire people who lack the ability to recognize that vast difference to work remotely. For one thing, you don't have the ability to compensate if you don't even understand there is something to compensate for.
Hell, I wouldn't even hire a person like that to work on site.
And the fact that there appears to be a strong overlap between people who favor remote work and short-sighted people who seem unable to recognize its disadvantages is not exactly encouraging companies to hire remote workers.
Yes, hiring managers read HN, and these kinds of comments aren't helping to promote remote work. Quite the opposite. The pro remote working crowd comes across as a bunch of immature self-entitled whiners.
