You should ask that question about every product you sell.
If it isn’t at least one of those, preferably two or three, then why do you have it? I’m pretty sure that unless someone thinks a product is interesting, cool and useful, you aren’t going to sell a whole lot of them.
Interesting gets their attention.
Cool makes them pleased they looked.
Useful compels them to buy.
I’m asking you the same questions about this blog. At the bottom of each post you’ll see a place where you can check Interesting, Cool, and Useful. Please tell me what you think (check all that apply). Feedback is always appreciated.
