I have gone back and forth on this issue of anonymity a number of times in my own mind and after reading here, I have decided to remove anonymous comments from the various blogs I control. This change is effective 3/1/08.
This is not turning away conversation.
This is ensuring that the conversation is based in honesty and real identity.
It also helps that Google has enabled additional accounts to be used to comment.
If you have any issues with anonymity, you can email me (as you won't be able to comment) after March 1. Email to shersteve at gmail dot com
