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.
