The word radish comes from the same root as 'radical' meaning 'root'. A radical is someone who draws attention to the root of a problem. At root, I am a radical and proud of it. Like the radish I tend to be spicy and am best taken with a little salt.
If you haven't figured it out from the title and logo, I also tend to pun early and often. If you simply cannot deal with puns: run screaming while you still can.
