I'm David. I co-founded and direct product/design for Next Big Sound. I check my email. Here are some things I've created. Follow me on twitter.
observing the internet
analytics: the number of times per day a person checks analytics and their sanity are closely related.
creativity: there are a ton of creative mediums, both to create with and distribute ideas. some work better than others.
feedback: user feedback is a mixed-bag, but generally useless unless collected and pruned carefully and intelligently.
traffic: not all traffic is equal. a stumbleupon or digg visit should be worth .5 or .25 what a regular visit is worth.
design: design is a little about how it looks and a lot about how it works. but it better look good.
risk: every action can be placed on a risk/reward continuum.
apples: some things suck when you start them, but end up rewarding. like eating apples - the first bite is full of skin, but by the end you’re glad you ate it.
browsers: cross-browser testing takes away time from focusing on building better applications and sites.
