This jQuery plugin generates sparklines (small inline charts) directly in the browser using data supplied either inline in the HTML, or via javascript.
What you're looking at is a personal aggregator of objects I've stored on various sites around the web. It makes it easier to point to a list of things I think are interesting and it has an added bonus of providing a way to use tags across all these different services. The list of sites are somewhere on this page (depending on what I finally did with the layout). I use these sites as most anyone else does. Use their forms or bookmarks or upload tools to start the items and at regular intervals this site sucks data about those items back into one database. I could make it sound really complex, but that would all be a lie.
