We design Britannica Online to work with 14.4-baud modems, since they are conceivably the slowest a customer would have. People think we're nuts to limit ourselves to worst-case technology, but we don't want customers to have to spend 20 minutes downloading an encyclopedia article. We'll take a long article and break it up so that each section is not huge. A different challenge is keeping the Internet systems running. When we do have outages, it's mainly hardware problems-a server or disk drive.
Fault tolerance is an ongoing challenge.
For the first time, we have a way to see what people look up in an encyclopedia. For example, we learned that when a historically based movie comes out, there are a lot of hits on the subject in Britannica Online. We're trying to capture those hits at a high level. We also want to look at queries where there were no hits. From an editorial standpoint, that information is phenomenally helpful in updating the encyclopedia and addressing what people want to see that we don't have.
