Exactly... I used to own spark.org a long time ago. The site never really generated a lot of traffic (about 150,000 page hits over its 3-year lifespan), but more than most personal website accounts (and more than a lot of commercial accounts) that the local ISP hosting spark.org had... A colocator or webspace provider's bread-and-butter comes from the vast majority of account holders that pay the monthly fees, but don't use hardly any bandwidth. This goes not only for the obvious "w3lc0m3 to JimMee'z Bon Jovi Fansite!!!111!!1", but for small businesses as well. Most folks don't go surfing to the website for, say, a local 4x4 customization shop, when it's faster and often easier to just drive down and have a chat with the manager about a specific need (like getting a new Detroit Locker rear-end for my Jeep, say...) Ergo, most of those sites sit idle, and do absolutely nothing at all but make the ISP money. It's the active sites that cost you as an ISP, which is why that cost is passed on in bandwidth charges. /P
