Do you feel less open about participating on public forums, publishing personal blog posts, or even contributing to open source? (I'm aware of the irony of asking the question here)
I'm definitely more hesitant these days to associate my "real" identity with my online identity. Easy example is I only access HN through a VPN and a pseudonym. I'm mentally prepared for the day that this account will be de-anonymised, and I don't post anything too crazy under this name against that day. Still, I'd prefer to keep a separation, and I'd probably start a new account if that's what it takes to retain anonymity.
None of this should come as a surprise. McLuhan predicted from the mid-20th century that we would end up with a global small-town mentality. The "global village" wasn't a platitude, it was a warning.
Almost a decade ago I made comments to political players I now regret. They were unkind. Their politics are shit and riddled with religious overtones but the comments I made were personal and objectifying.
I don't want to be associated with those remarks, and in a pre internet world people got to be forgotten for their mistakes and mispeaks. Now it's far harder.
