My pseudonym is my authentic identity on Reddit, just as it is here on HN. A while ago I was using one identity here on HN and for one reason or another, some people didn't like what I had to say (even though personally I was very authentic) so they down-voted me so much that my score went in to negative, and I ended up deleting my account and recreating a new one. I have still not given up on being authentic under pseudonym.
The point is that you have to believe in the conversation - gaining and imparting knowledge - and not worry about the fluff and the other distraction of the Internet. The trend to have real names on the Internet, the trend to have face on the Internet....these are all distractions as far as I am concerned.
As long as we are typing and reading each other through letters and words, we don't need to see each others' names and pictures. It would be a different matter when we converse through video and audio.
