ListMixer does simple, disposable web-based bookmarks
Add the ListMixer bookmarklet to your browser, click it once, and your unique ID is created. There's no registration required to start adding links. Once your mix has been created, you can add sites to it by clicking the bookmarklet.
You can add a tag items to group them on your mix page. Only a single word or phrase is supported, but it's enough to get the job done. Tags you've used previously appear in a drop-down box when adding a new link. Descriptions can also be added to your items.
ListMixer also supports hotkeys: holding 1 down while clicking will add a page to your mix and immediately return you to that page. Holding 2 down automatically adds the page and then displays your mix. To view your mix without adding a page, hold 3 while clicking. If you'd rather just click away, additional bookmarklets are provided to perform the same actions.
An RSS feed is also provided for your mix, and there's also a handy tool for creating a linkroll to embed on your blog.
