> strong decisions that WILL alienate people, but will better target your intended audience. That, IMHO, is a great thing

That's supposing you have a well defined intended audience. Many people see it as a prerequisite, that's also how we ended up with the personas during research.

I'd argue there are many designs that should go beyond a specific intended audience and allow for larger reach and minimize alienating people. My reasoning is that in part we're just not good at properly analyzing requirements (it's just hard) and people's needs are also volatile. Trying to design the perfect things for a narrow target often results in something just really bad.

As a concrete example, mouse makers targeting specific hand size and shape for specific actions usually end up with a worse product even for their intended audience. Having more leeway to hold it differently, change the way you use it e.g. depending on the time of the day or task at hand is just more comfortable. The best mouses on the market are pretty forgiving and flexible. Heck, the most clamored pointing devices (Apple trackpads and Kensington style trackballs) are completely hand agnostic.
