I love the idea…and ask why it doesn’t have tagging and an open API for the data.
I’m looking forward to Richard’s further posts on Yellowikis – the site has been up since January and has very thin data right now. My recommendation – tweak the model (as I mention above) and get the network effect flowing. I will gladly profile it on TechCrunch at that point.
By the way, I forgot to link to Richard’s Web 2.0 Weekly Wrapup for last week. Check it out (and subscribe) here.
