Pinterest is social bookmarking and is (obviously) incredibly popular. Delicious pushed "tags" as its killer feature. But if it had dumped putting tags front and center, and instead focused on beautiful photos of the items bookmarked, maybe it would have taken off more.

I've already up voted you, but have to praise this insight. Folksonomy is a wonderful navigation and subscription method for the early adopters, but I still hear my wife telling my son to "search for a recipe you like on Pinterest". It's perhaps the Yahoo! vs. Google aesthetic in the sense that Delicious appealed to curators who were comfortable navigating by concepts, while the rest of the world just wants to find a like-minded, curated world that they can navigate by search.

I don't think tags were front and center.

We wanted to do images; the delicious predecessor did have inage capture.
