Our mashup Annotated links has been updated. Lets you pack any link (group of links) and your own text comment (in post-it style) into one short URL. The final pack could be shared via email and twitter. So you can threat it as yet another way for link sharing in Twitter for example – your comment could be much more than 140 chars.
You can annotate links right on the site, via bookmarklet or via HTTP API.
