There is one thing about Clipmarks that really bugs me, though: You can easily clip and save content to Clipmarks and then e-mail or blog it, as I said above. But once you leave the page you've highlighted clippings on, they vanish. To me, that's like having a highlighter with disappearing ink, which is not really what one expects: You highlight some text, turn the page, turn it back, and presto! your highlights are gone. I'd like the option to make Clipmark highlights persistent. Annotation services such as Stickis and Trailfire do this, but they're designed for a different purpose.
