An invitation-only app spreading by word of mouth takes up half of this small blog, complete with a warning that you lose your place if you do not respond within a day. Guy Monague was clearly caught up in it, and reading those posts now is a useful lesson in how urgency gets manufactured.
The better material sits underneath. His post on breaking old habits leans on a neuroscientist rather than on willpower, and treats a habit as something the body runs rather than something you decide about each morning.
He also writes about what actually makes somebody join a team, which is a more interesting question than how to recruit, and about finding things to write when a blog is new and the well is dry.
There is a joke post written from the point of view of his dog, and it is funnier than it needs to be.
Read the habits post. Read the app posts as a case study in urgency.
