You can re-create the same thing manually.
1. For a particular quip, move your mouse to the right of the “Flag as…” link, see the ¶ symbol pop up?
2. Right click on the ¶ symbol and select “Copy link address” from the menu (depends on browser). [ – OR – simply click on the ¶ as normal and the browser will reposition the page to put that quip at the top. Then just copy & paste the url from the browser’s address field. ]
3. Click on the person’s name to get to their comments page where you can leave a message.
4. Type your message as normal. For the link portion, just follow the textile rules: doublequote, text to link, doublequote, colon, url.
==> ” text ” : http://fluther.com (but without the spaces I embed here for clarity)
==> link to your quip here.
