Every time someone makes one of these I'm just dumbfounded by how much money there is in it. I mean granted, they're sideline businesses for the three I'm most familiar with, but they are sideline businesses which would pay for almost a full engineering team...
They kind of have to be sideline businesses. Expensive niche job boards work well only if you already have a valuable community and reputation. They can't be created out of thin air, you need to have "main business" to piggyback upon.
Most of the value is created elsewhere, job board just helps with extracting it.
