I quite like what Brent Simmons has done with his ‘What I Do’ page to explain his mysterious and important work:

I know I’m a big nerd and what I do must seem all super nerdy and vague — and it is pretty nerdy but it doesn’t have to be vague. I’ll explain what I do and why. 😀

I do two main nerd things: write a blog and make an app.

A fun way to reveal the non-obvious parts of what you do for curious friends and family, and squash misunderstandings. A candidate for a new @robb@social.lol Slash Page?
