After glean becomes a bit more comprehensive, it would be nice to accumulate results and make them accessible through a website. For example, if you're considering buying a graphics card, or you want to survey all cards to see whether you can count on using a given feature, this website would be the place to go. Creating an index for this database would be an interesting challenge; at the least you'd have to deal with glean version, CPU type, graphics card type, OS type, OS version, and driver version; maybe graphics chip revisions, too.
