What do you do if your product or service is not loved by customers? What determines that the stuff you buy actually gets used? Where is the line between shelfware & wonderware (okay, I made this term up, but you get the idea).
Here is another one of the heuristics / rule of thumb (okay, rule of thumb & a finger) that came out of one of the rants on what can we make that folks would love.
Hope this makes sense.
