Minor changes

I added a comment preview so you can see what something will look like before you hit submit, so that’s good. Also a linkroll of things i digg at digg.com. I like that site pretty well as my community aggregator right now, it’s kinda like a metafilter without the people interacting in any long term get-to-know-you sort of way. Most people compare is to slashdot, but it’s much simpler than that. It’s also not some new fantastic idea like some people in the press seem to think, slashdot, plastic, kuro5hin, metafilter. It’s good but it’s not revolutionary just because it uses ajax.
