It has some job postings yes but they are really few and far between. And really inconspicuous. And don't try to track us across the internet.
If all ads were like this we wouldn't hate them.
And I don't think they will start. It's good advertising for Ycombinator (I'd never heard of them before) and it doesn't cost a fortune to run really. They have one employee (or maybe 2 now?) and it all runs on one physical server. It's not a meta with a huge workforce and offices and datacenters all over the world.
