Listography.com lets you keep a database of lists in an extemely simple and clean interface. With Listography you can keep conventional practical to-do lists, but it also encourages creative list writing (there are dozens of categorical prompts).
In the last week it became one of my favorite web sites. My mind already operates visually in lists, and I’ve always scribbled on messy post-it notes. The site looks awesome and bridges the gap from chaotic creativity to ordered productivity. Digital lists are a little more organic than paper because they’re unresolved (easy to access and you can’t run out of space). Plus, since nonlinear appending isn’t sloppy there’s less distraction in the way I extract stuff from my head.
Right now I have the following running lists: things I’m waiting for in the mail, things I need to buy, favors to do for friends, albums conducive to hanging out, favorite condiments.
