i'm working on an informational site that will target individuals looking for schools. i want to attach a blog to the school site. when i add the blog, i'm thinking of putting it on as a link (obviously) in the school site. but should i link the blog to a subdomain of the school site... or should it be to another domain? the thing is, the blog won't just be about school, it's going to be a general blog. i think it would just be easier to remember if the blog was on it's own domain.

second question, if the blog is on a seperate domain, does that require another subscription to a web host or is there any way to link it to the school site subscription, or does it depend on the host? (this is probably a stupid question, but bear with me)
