Rands In Repose interviews the creator of Instapaper, Marco Arment.

When asked about the early decisions he made in order to manage as a one-man shop:

The biggest design decision I’ve made is more of a continuous philosophy: do as few extremely time-consuming features as possible. As a result, Instapaper is a collection of a bunch of very easy things and only a handful of semi-hard things.

Keep it simple, iterate.

…losing your read position is a form of minor data loss.
