Very often I see some stupid error messages as a (power-)user. I do not know if this is because of lazy developers or managers not having enough focus on more useful error messages.
If the error messages would be more clear it would help me as a power-user to fix my problems faster and fix it possibly myself instead of asking questions or even open support cases.
That would also safe costs on the support service side if end-users would be enabled to fix their problems themself. If this is what software vendors really want...
