You're not part of the target market, then. Think of it like any other recurring service, e.g., pickup/drop off laundry. It costs way more than doing laundry at the neighborhood laundromat and doesn't save very much time, maybe a couple hours a week. But, if you don't enjoy doing laundry, and you don't have an in-unit washer dryer, it may be worth it.

If you really don't like using your brain to write, then why not spend a bit of money to offload some thinking to this service?
