I am assuming you will be the admin and the other writers, contributors. You should make it clear that the posts go through a review process before publishing. You can always ask the writers to make specific revisions, as well. And even suggest specific topics for them to write about. You just have to be confident and don't be afraid to give direction.
If you have poor literary taste or bad grammar, reviewing their work may not be a great idea, though.
A vast majority of all of the extremely popular blogs across the net have just a couple of things in common; impeccable grammar and spelling. Writers who cannot spell or write properly appear less believable, thus making reading their writing a waste of time, somewhat.
Instead of blogs and bloggers use words like articles and writers.
But I agree with the post above, you must peform a vigorous copy editing role. Copy editing includes spell checking, fact checking and grammar checking. When you read blogs you should be thinking 'that fact has not been checked', 'that sentence should be re-worded', 'surely separate has two 'a's' etc.
You should be vigorously copy editing everything, spiking articles that are not up to the mark, giving your team direction on subject matter etc.
Copy editing is a full time role, as is recruiting good bloggers, as is planning, as is building advertising, as is blogging yourself. Do you see where this is going?
