Looking for Spock here? Live long and prosper, my friends.
I specialize in Usability, Human Factors Engineering, and User Interface Design.
The StackExchange sites can be a great place to share knowledge and learn new things.
Due to some rude and inappropriate moderating of the Superuser StackExchange site (a sentiment unfortunately shared by quite a few people), I regret that I will be limiting my contributions there. I do not share those values. Hopefully things will improve.
The other StackExchange sites seem to attract much better quality and more friendly moderators, and thus have healthier communities.
