Without getting into the ideological minutiae, is it not possible for the government to know that there's something wrong in the marketplace, and not be obligated to address it?

It should be possible for both the FCC to acknowledge that censorship by large, private, commercial entities is bad for free expression, while acknowledging that it is their platform to do with as they please, IMO.

Worth noting that while side and back windows are tempered, windshields are typically laminated.

The difference is in how they break. Laminated glass will generally crack, but otherwise stick together, while tempered glass will shatter, but into less-sharp pieces (to minimize the hazard of broken glass).

I don't know how much of this matters, but it stands to reason that what works on a side window might not be the same as what works on a windshield.

If you know which comments on a page are new, then you also know which ones are old. The easy answer is to just gray out the older posts (only remotely challenging because the gray background of the page is about the color I WOULD have suggested for old comment text) -- and just leave the new comments as they are.

That allows you to easily skim the page for new content, while still allowing you to see the new posts in context.

A Digg-style collapse would also probably work, but for some reason, I see grayed out text more in line with the ycombinator mantra.
