This is a hack on top of Jeff Howard's excellent bookmarklet.

Jeff's bookmarklet generates a quote in roughly this style:

Jeff Howard: Just drag the bookmarklet into your bookmarks bar in Safari or Firefox.

Changes:

> Just drag the bookmarklet into your bookmarks bar in Safari or Firefox.

It'd be nice to move cursor position to the end of the comment, and insert carriage returns, and add the comment ID to the link title. Managing CRs in bookmarklets is painful. The other items I'll try some other time.

Drag this bookmarklet to your bookmark bar.

In Safari, any bookmarklet can be invoked from the keyboard if it's in one of the first nine items in the bookmark bar. Hit cmd-1, for example, for the first item. This allows access to bookmark(lets) even when the bookmark bar is hidden.

August 10, 2008: Exclusive for willing test subjects!
A new version of the bookmarklet. This addresses most of my complaints noted above:

This has only been tested on Safari 3. Users of Mozilla and Opera are encouraged to report problems. Users of Internet Explorer continue to be out of luck. If you are willing to help out, drag this bookmarklet to your bookmark bar.

August 11, 2008: Updated! TWICE!
Drag this new, improved bookmarklet to your bookmark bar! Yesterday's version was as fast as hitting cmd-1, but today's is even faster! Seriously. I replaced roughly 30 lines of sequential and nested loops with one if/else statement, sparing your browser some heinous memory caching too. So if you grabbed the earlier one, upgrade now. Also, Today's first posting contained a bug. UPDATE AGAIN! UPDATE ONE MORE TIME! Because the 'update again' version had a bigger bug than the version it fixed. Yes, that was lame.

Footnote:
* The current official bookmarklet would cite the last person to use a particular phrase. It works badly with text selections involving very short or repeated phrases. This new version cites the person in the "posted by" in the text you copied. It
will not attempt to trace backwards any quoted text in somebody's comment.
