Well the first site I hosted was on shared hosting for free. I had dial up, so hosting it on my own PC was not very practical. I didn't know about server administration, but knew how to write PHP, so this was perfect for me.

When I got a job in a supermarket at 16 earning £4/hr I was able to afford a VPS, so bought that and learnt how to administer servers. To me it was a worth-while expense as a fun hobby and education. Today you can get a more powerful VPS for $5/mo, of even free with things like AWS free tier.

I'm not sure that's really applicable to Zuck and Co (it wasn't just him when it launched) though - someone at Harvard with wealthy parents.
