My situation is very similar to Mikesinner's; I've got a fairly large network of blogs on freehosts and want to take it to the next level. There's some great advice here which mostly seem to fall in two camps:
- 1 blog per domain all hosted on a virtual server.
- Multiple subdomain blogs on a single domain with WPMU.
Either way, the general consensus seems to be to get your own hosting and domain(s).
I'm prepared to take that next step today, but before I do I'd like to know which of these options is generally considered the better?
