By now, many social media managers have realized a hardnosed reality: Most subject matter experts within the corporate walls don’t have time (or the skills) to blog. So you have two choices:

• Write/edit their blogs for them (and give up the rest of your life since writing is very time consuming)
• Hire a specialist or “real writer” to write for them.

That would be a journalist or professional business writer. (I use these interchangeably, even though there are some solid business writers who were never journalists.)
