That’s what Joe Donatelli says. He adds:
For writers, there are two problems with the pay-by-the-word scheme. The first is that it assumes all stories are created equal. This is problematic. As our example above shows, all stories are not created equal. Some can be written relatively quickly. Some take more time and effort. Can you spot the incentive?
The other problem is that pay-by-word assumes that all writers are created equal.
