It would indeed be rather stupid to call my home page a text hosting service.

Er, the range of the customer base is not involved in the definition of hosting service. Hosting services need not target the general public - they target whoever they think needs their service. There are all kinds of exclusive hosting services out there. If you think otherwise, surely you ought to at least support your strange idea with some kind of reference.

I didn't really implicitly compare with YouTube - rather I explicitly compared with YouTube - mentioning their service by name. Both sites host videos, though YouTube has a much better player and search facilities, and is much closer to being unmoderated and uncensored.
