That must be the difference (or I was blocked by some filter). I didn't try to make a social-media call-for-action, because I didn't want to trigger voting-ring protections.
EDIT. As for the filters... PH doesn't allow comments which include "ps aux" or "curl" strings. I learned this by studying HTTP responses using Developer Tools, because the error was not signalled in PH's UI :).
Any decent comment system should accept that kind of comment without choking on it.
This "Mathew effect" is the case with a lot of things – book deals and record deals, for instance. Unknown artists occasionally do get their big breaks by being in the right place at the right time. But if you're managing one (even if it's yourself), it makes sense to improve your odds by being systematic, and yes, basically cosying up to the gatekeepers whoever they are.
