I think it's respectable that you gave a disclaimer that you worked there in a thread about Facebook's use value. It's a little unlikely that doing so wouldn't result in an accusation of bias, too. It certainly should not be the basis for an ad hominem against your response. So it brings me to, why mention it?

Not a disclaimer, but a disclosure :)

The reason I mentioned it was because it was rather relevant to my having the incentive to remember the timelines of FB launching various features almost a decade ago.
