I've now started feeling that keeping a wiki is paying off. I've noticed it's starting to act as an associative memory. For a long while it's been useful to catalogue my ideas and the connections between them, but mostly when I go to write a page I ususally have, in my mind, the connections it will make with others.
But over the last month I've noticed a change. Maybe this wiki has hit a critical mass. (CommaCount? 462 pages, SpaceCount? 686 pages) Now I'm finding I enter a page and have in mind a number of links to make to other pages, but when I follow those links, I find the second (and higher) order connections genuinely surprising and flooding my mind with ideas.
