Ubiquity Means Popularity (Obviously)

Techdirt posted an article yesterday pointing to a new study that aims to prove that 'popularity begets more popularity' and that obscurity is one of the main factors that inhibits popularity. Therefore, the implication is drawn, lesser-known artists should give their product away for free (in doing so becoming more popular that will mean more popularity that will snowball into a popularity landslide and they will eventually be the most popular person ever).

Nothing too suprising, but its nice to have facts and figures to back up opinions.
