What's wrong with just being a stable place? Why does everything have to evolve? Craigslist works fine for a lot of people. It is familiar, doesn't hog bandwidth, and doesn't leak personal information like a sieve. Sometimes a hammer just needs to keep being a hammer.
Great point. I think this concept of "disruption" is out of place anyway when the existing site is mostly free and works fine on mobile devices. You might be able to steal traffic bit by bit by doing a better job, but there's nothing to really disrupt in a dramatic way.
