Earlier quoted context omitted.
Yes I understand the rationale behind “lots of bodies”. As OP was rightly pointing out, there is a discrepancy here between output and size. LinkedIn for example has many of the same issues and a lot more complex functionality. They manage to do this, compete with Indeed (and have a higher market share), with a relatively small number more people.
LinkedIn doesn't have no where near the market share of job search / hiring in the US compared to Indeed. It's like, 2-3x less.
Job board popularity varies greatly by country, but from the look of it LinkedIn has more of the global market share of Indeed.
My point is that unlike indeed they do this without jobs being the core, 100% thing they are dedicated to. Even if they are slightly behind in market share the point still stands that LinkedIn is clearly doing more with less.
