Dien, this is very interesting. A few years back I had a website Top 12 Daily or some such (lost interest after I missed one day and then another and then another...).

Lists of Ideas have always been easy for me. Implementing them if they were implementable, well, not so much.

Just today as I was thinking of an upcoming move, I wrote (during lunch at a sandwich shop so I had limited time)
10 Reasons to Hire Movers
and
10 Reasons NOT to hire movers.

While I was in that mindset, I wrote

10 reasons to ask friends to help you move,
and

10 reasons NOT to ask friends to help you move

For each of those lists, I got to about 5 or 6 easily and was stumped. Then the creativity kicked in.

I'm going to explore this notion of ideas being used as currency.

Thanks for mentioning his site.
