I agree 100% (and great article!). It really goes back to the value piece. There are hundreds of directories online and even some businesses who have "directories for sale" essentially (they sell emails or, in Crunchbases case they sell hard to find on your own information) but what's missing is the value add. What's missing is the matching.

This is awesome insight and helped me re-position my thinking on the UVP of my marketplace idea. Thanks again!
