Consider this: You made all the required mock ups for commissioned layout, got all the approvals, built a tested code base or had them built, you decided on a content management system, got a license for it or adapted open source software for your client’s needs. Then the question arises: where’s the content? Not there yet? That’s not so bad, there’s dummy copy to the rescue.
But worse, what if the fish doesn’t fit in the can, the foot’s to big for the boot? Or to small? To short sentences, to many headings, images too large for the proposed design, or too small, or they fit in but it looks iffy for reasons the folks in the meeting can’t quite tell right now, but they’re unhappy, somehow. A client that’s unhappy for a reason is a problem, a client that’s unhappy though he or her can’t quite put a finger on it is worse.
