The series sounds like it could be really great, I wonder if they have a frequency for new interviews planned already? The series title alone got me though, as someone who is working on a startup that is something I really aspire to be, profitable and proud.<p>Campaign Monitor is a great service too, I frequently reference and share their Guide to CSS support <a href="http://www.campaignmonitor.com/css/" rel="nofollow">http://www.campaignmonitor.com/css/</a> to coworkers who have questions on what can and can't be done with styling in emails.
This looks like it could be pretty interesting. 37signals feels like something of an outlier to me: they talk a good game, but I don't really get the feeling that I could do something similar, because I don't have a hugely popular blog, nor did I create an extremely popular web framework.
