I don't get spam.
My school/work address has a pretty good spam filter anyway, but I have the option to disallow third parties from obtaining my email address via the university. Between those two, I get maybe 5 filtered messages a month in my junk email folder at school/work (same place).
I get a lot of work related status messages-- this server is down, so and so changed shifts, meetings or training coming up (although most meetings are just added to my calendar these days), new features added, etc. I have many of those filtered on the server because I really don't need to do anything with them when they come in.
It is rare that I need to reply to an email, and when I do it's usually a yes or no answer rather than a conversation. I think the last email conversation I had was in 2003. That's probably the last time I was on a non-work related high-traffic mailing list, too. Conversations now are via texting, Facebook, or Twitter; rarely by phone.
You're not supposed to read every email. I haven't done that in years. In an average day, I might read 5-6 messages. I scan subjects. Newsletters and such I read on the web, usually through Google Reader.
Author of TFA was either BS'ing to sell advertising space or BS'ing to get on /.
OR, the author of TFA is far enough behind the times that he still hasn't mastered this online communication thing yet. Perhaps he should ask his kids for help.
