Expert networks are everywhere. The “idea” site, PSFK, appears to have launched its very own, which they named purple list. The name appears to derive from the color-scheme on PSFK while providing a new spin on expert networks – a go-to source for new
ideas and inspiration.

Purple List has a similar look and feel to Quora, G+, or Focus, and it’s organized along the lines of Intota’s directory model. The about section suggests that they will charge the respective expert for listings, and those needing new ideas and inspiration can peruse profiles for free.

Sadly, a paid listings model will probably limit the opportunity of this marketplace. It’s just hard to say what an expert would get for their $20 profile.
