37 Signals has a post today where they poo-poo personas

We don’t use personas. We use ourselves. I believe personas lead to a false sense of understanding at the deepest, most critical levels.

Every product we build is a product we build for ourselves to solve our own problems. We recognize our problems aren’t unique. In fact, our problems are probably a lot like your problems. So we bundle up the solutions to our problems in the form of web-based software and offer them for sale.

So I buy in that you can/should build software that scratches an itch. I also can understand why it is powerful when it’s your itch but are they really saying we can only build software for ourselves? Note to self: good thing I consume a lot of RSS.

Seriously though, a lot of useful software would never have been built if this were the case. However, I suppose you could argue that there’s a lot of software built that shouldn’t have been.
I wonder what my former colleague Robert Barlow-Busch thinks. Bobby, what say ye?
