Google has high hopes for their Google Base as you can glean from articles like this one.

Perhaps it will be an eBay killer. Perhaps not. In any event, it is a great repository for product information, classified ads, recipes and so on.

I would love to see Google Base used widely for the dissemination of lesson plans, where teachers would share their lesson plans with other teachers from around the world.

I think Google should not only encourage this, but also launch a program to facilitate it. At a minimum there should be a category called “Lesson Plans”, because a search doesn’t return anything useful. And Google should seek out teachers like they sought out video content for Google Video.
