I don't think Apollo is just a hobby for Christian, given that he said that working on it is now his full-time job.

Trying to start a new social network (or whatever you'd call Reddit) from the ground-up is not only very likely to fail, but it's also a totally different skillset than building iOS apps. Of course he'd rather just find another job.

His point was that there is a big difference between building a product and operating a service. I can understanding not wanting to do the latter, because it's a COO job and unless you like doing that it is not fun.

And frankly it's a failing of society that we would ever need to.
