Lefsetz's rant against forcing him to use Facebook has this to say about curation:

I don’t want digital recommendations. Anybody actually use iTunes Genius?

That’s why I hate Pandora… Seemingly every suggestion is a tune-out.

Then again, I seem to be the only person who gives a thumbs-down to the site. Everybody else is complaining they don’t know what to listen to on Spotify and they want algorithms to hip them to what’s good.

But algorithms never work, not consistently enough to invest your listening time. The filter, when it arrives, will be based on tastemakers, not data. Data might help, but it will never rule supreme.

I’m sick and tired of having to protect my privacy. Facebook is one giant cesspool whose raison d’etre is serving up targeted ads based on what I do on the site.

But it’s worse. We don’t even get the same Google results. Yup, you and I can put in the same search terms and get completely different listings. And no one clicks on anything beyond the first one anyway.

Hand curation trumps algorithms when it comes to taste.

That's why we trust editors and experts so much as taste makers.

They cut through the noise.

Technology is a pendulum between algorithms and human experts.
