When Dave Stoller grew up, he kept spread sheets and put his bills in a filing cabinet...perhaps you mean Peter Pan?

They can be updated easily and from time to time - it's nice to know what I have. It's also interesting to see how I view fluctuations over time. If you find it "Dave Stoller" to buy a campy umbrella clamp when you already have one, great. I think it's incredibly stupid, a waste of money and I find it useful to have an easy repository of what I have. It also gives me a fast place to look if there are trade offers, or WTBs, or to quickly check what I can part with if I need fast bike funds. It's fine if you don't find it useful, but obviously some here do.
