"The best recommendation tools perform a balancing act: They connect to consumers' sense of individuality as well as their group identification. Similarly, the tools must come up with recommendations that stretch horizons with suggestions that are new and a bit surprising, yet not off-putting. Recommendation approaches vary in how much access to the "long tail" of niche or obscure products they provide. Most recommendation engines offer a balance of the familiar and the unexplored."
Passion lives with diversity on the long tail. Yep, it's an adventure going there. I discover awesome things - from niche markets - that blow me away and really cool people - bloggers - who have mind-boggling ideas about everything.
