Today, a company can tell you, in real time, how many visitors its Web site is getting, how long visitors are staying, and how many pages they’ve clicked through. Unnerving, perhaps, but monitoring such metrics also means we can find out what you're interested in. Thanks to Builder's reader service bureau, Inquiry Management Systems in Toronto, for example, we have a very accurate picture of what products piqued your curiosity over the course of 2008.

And compiling lists such as the Favorite 50 reveals a lot about where the industry’s collective head is at. For example, last year, the popularity of tankless water heaters and in-floor radiant heat reflected the growing interest in energy efficiency, while folding patio doors spoke to the indoor/outdoor living movement. This year, energy efficiency and sustainability are still hot, but take a good look at the rest of the list and other trends will emerge.
