(Insert title here)
The current avatar is from the comic strip Perry Bible Fellowship. It's a good strip, but that particular one cracked me up, and we were coming off the Hammer demonstration, so I figured to go with something new. (It had been a picture of my daughter for a few years.)
The motto—"Stop pretending you're stupid!"—came about in response to one of my Sciforums neighbors who was pushing what I thought a slightly irrational line about user titles. The phrase isn't actually directed at that user, though. It's directed at the community at large, mostly because it would be inappropriate to publicly single out the users who most need to be reminded.
And my user name derives from the fiction of Steven Brust. What can I say? I like Tiassas. They're easier to get along with than Dragons or Dzur, more trustworthy than Jhereg, and very possibly as faithful as Issolas.
