Show HN: I made a tool to hide HN usernames and reduce bias

Hey HN, I made this tool after I read a pretty interesting pg essay - http://www.paulgraham.com/hackernews.html

He talks about changing some HN usernames' colors to orange and then deciding to revert back

So I thought it could be interesting to remove usernames entirely. This Chrome Extension just replaces HN usernames with question marks. I've enjoyed using it so far myself and I'm curious what you think about the concept?
