What are you talking about? There are literally hundreds? What’s not viable about them?
Ok, I understand your frustration. I’ve already mentioned in another comment that I used the wrong word. Thank you for bringing it to my attention. In the future I will use the correct terminology as to not frustrate you or portray a message in the incorrect form. I hope that I have caused you no inconvenience and wish for your forgiveness. Please do not hold these actions against me, as I do not intend to make such embarrassing and hurtful mistakes in the future.
It has everything to do with viability. Something is not a viable alternative if no one can be convinced to use it.
