I find that longer content works better for me when trying to understand important concepts. I generally need repetition and context (why is this a valuable concept? how'd you get here?). While it's quicker to digest bite sized audio, I tend to forget the takeaway easily.

Have found these links to be helpful in understanding the concepts here:

Is this a problem people are willing to pay to solve? Is the fact that it's raining outside a good enough reminder not to lose your umbrella? Just curious.

It wasn't raining when I left home this morning, so I didn't bring an umbrella to work. It's raining now and I need to walk home with no umbrella.

Still doesn't mean that I'm going to buy one of these.

It's cheaper and easier for me to just lose my umbrella and buy a new one if that happens than to pay $60 upfront

People often carry umbrellas in areas where rain is less predictable. I've left umbrellas in restaurants etc. before, but...

a) I know where I left it, and

b) a decent umbrella costs $3 where I live, so I'd need to lose 20 before this became cost effective.

Wouldn't the pay off be not getting wet when you would've forgotten an umbrella? It's not presenting $60 in umbrella value, it's availability/convenience value.

We recently launched (http://www.robotoatmeal.com/pages/about/) to address this. We're addressing the scam coupon issue by surfacing real time usage data. We also try to validate the coupon before it's published on the site.

While I think we can definitely do better (the data is pretty sparse in some areas), I believe the collaborative / real time validation approach will lead to a better experience for shoppers.

Ditto. Amazon makes it so easy to buy.
