Personas are not meant to represent one person or user. They are meant to represent classes or segments of users. This is a valid use of them. Creating stereotypes and aggregates is useful in many endeavors. You by default will always design for someone- question is whether that person is the developer, founder, CEo or his daughter that is positive some feature will be kewl. Those methods have worked- it's like like design by developer doesn't create smash hits like basecamp by 37s - the problem is that no one besides them finds their INS models particularly usable or intuitive and barely learnable- their breakout success maybe more attributable to their business model or the eloquence and celebrity stature of the founders but not by any metric a Ux professional would call repeatable and predictable.

That's an interesting article, but I must admit it has me confused
as to whether personas would be an attempt at validity or
reliability. I see personas as an attempt to represent a product's
users, the goal being to reliably categorize users into types so that
the product can be designed to fit those types. I see that as putting
the method on the reliability side, although I'm uncertain as to
whether it actually is reliable.

Or looked at from another angle, can personas be considered valid if
they don't represent actual users?

Thank you for the link.
