Really sage insight from Dave Winer:
You only learn where a product needs improvement through serious long-term use…
This was a secret of mine, because most of my competitors not only didn’t listen to their users, but they didn’t even use their own products. If you want to make great products, never mind the degree in finance or marketing, though those skills are certainly important to running a business. Be both a user and a developer. That way you understand users, and you can make their dreams come true, because they are your dreams too. The reward for that is success.
I’ve often found it surprising that most researchers don’t actually spend very much time with their interventions. That’s a real problem. If we don’t use them, why do we expect that others will?
