Why restrict to 54-bit signed integers? Is there some common language I’m not thinking of that has this as its limit?

Edit: Found it myself, it’s the range where you can store an integer in a double precision float without error. I suppose that makes sense for maximum compatibility, but feels gross if we’re already identifying value types. I don’t come from a web-dev/js background, though, so maybe it makes more sense there.

Seems a bit disingenuous to compare the niche of tech folks that used Google+ to the niche that use WeChat, with the later “niche” being… China…

Not everyone has to agree that dominating a country’s social media usage is a good goal, but it clearly is the goal for many companies, and they’re going to continue to persue it. Perhaps users of social media should redefine success, but for creators of social media platforms there are absolutely clearly defined measures of success and failure.
