I'm pumped for Disqus. Use the time in Cambridge to focus on building a technology war-chest. You'll never find the time to focus on code the way you will during SFP.
Is "disqus" good? I'd try to avoid any name where the spelling has to be given, "It's disqus.com, spelt...". That said, it's very hard to come up with a good, available, .com these days. Before I went off and found out the site's purpose, I thought it was a corruption of "discus" rather than "discuss". Silly me!
