+1 Except AFAIK Des only ever wrote 2 posts that were in any way "promotional". And even at that, they're pretty damn classy posts. E.g. this is the other one and it's been one of the most popular posts on the Intercom blog to-date: http://blog.intercom.io/automated-emails-customer-respect/ But isn't any post on a company blog a promotional post in some way? (Maybe not.) Disclaimer: I work at Intercom.
