Hampton Lintorn Catlin
Hampton Catlin is the co-founder and CEO of Wordset, an online collaborative dictionary, and rarebit. He is also the inventor of Sass, Haml, and m.wikipedia.org . He's the founder of the libsass project and the author of "The Pragmatic Guide to Sass." He was formerly mobile lead at the Wikimedia Foundation and CTO of Moovweb, helping large companies build better interfaces.
Also, my husband, Michael Lintorn Catlin, has a blog you should checkout if you want to follow what we're up to, non-professionally.
I wrote a pretty in-depth overview of Merb over at Rethink for anyone whose interested.
