Devil's advocate on the pen names though....

Let's say I want to build a niche around "guns" but I don't want anyone to know my real name. (...just call me 'ShotGun Fred') ;-) When it comes to social media, article marketing, responders, networking, etc....are you suggesting that I need to have another 'fake' account with all of these things?

Soo...
(2) Twitter Accounts
(2) YouTube Accounts
(2) Email Accounts
(2) FaceBook Accounts
etc, etc....

Randall
(my real name!) lol
