I think that's the easiest solution. Twitter and Facebook have two different atmospheres - you don't get 20,000 followers because you have 20,000 friends, but because you have 20,000 people interested in your role as a professional authority and your posts about product trends, etc. Similarly, Facebook isn't tailored to disseminating a lot of information to a lot of people quickly and consistently - the number of people who'd really care about your personal life is almost always much lower than the number of people interested in new product information from your company (presuming they have a professional stake in it).
Though, in my case, I'm still working on establishing my professional authority on Twitter… :) As a matter of fact my number of Facebook friends and Twitter followers are dangerously close.
