Give the once over - pricing of songs is determined by their popularity. The people behind the site say that their experience has shown that when the price drops people diversify their music portfolio. Hear that RIAA?!?!? When the price is LOWERED people buy MORE and DIFFERENT music!
**Scary cool thought - how about real-time pricing of learning content? Think about the diversification that could take place, the 'bio-diversity' in the 'learning ecosystem' that could present itself if developers instead of just taking the most popular and hence the highest-priced content, looked around more and discovered those nooks and crannies hiding some previously unknown learning gems [see craphounds].
