In long threads, the back-and-forths that arise can be hard for others to follow. I try to make a habit of linking back to and/or quoting the original comment, but the formatting can be a nuisance. This userscript adds a link to each comment to auto-fill your reply with those details. [more inside]
A Greasemonkey script that allows adding custom tags beside usernames. It places a small link after usernames on posts/comments which can be clicked to open the tagger UI. From here you can create the tag [text and color] and it will instantly be applied to all occurrences of this username. Clicking an existing tag will open the UI again to edit or delete it.

Seven current Greasemonkey scripts and Chrome extensions written by me, six(ish) following the request of MetaFilter users. These scripts and extensions have been successfully tested with MetaFilter after its recent redesign, including support for both the modern and classic themes. [more inside]
I spent some time writing a Greasemonkey script that allows a user to modify the number of comments shown on a metafilter post by the number of favorites it has received. This work is based heavily on previous Greasemonkey scripts (thanks go to Jordan Reiter and Jimmy Woods) which were no longer working on the new modern theme. I've added in a few new features as well. Works on all the subsites that have comments. For a full description and some screenshots, please view the Greasy Fork page. [more inside]
A new Greasemonkey script that keeps the titles visible but makes them less (in my opinion, and no offense) obtrusive. It moves them down to after the main body, and just before the "posted by" line, in italics and the same font size as "posted by". It works on the blue, the green, and the gray. Screenshot here.
This is a new Greasemonkey script that looks through the current Metafilter page for links. It puts copies of any that it finds (except for stuff like "posted by Somebody at 12:34") into a sidebar on the right of the page, under "Tags" (and whatever other stuff may be in that area). Also, if you hover your mouse over one of the links (in the sidebar), a popup tooltip will open showing more context (i.e. the text of the comment that the link was from, albeit a pretty poorly formatted version of that text (sorry)).
I wrote a Greasemonkey script that lets you, on-the-fly, modify the "favorites" label on comments. Originally written because the November experiment's "faved" was unpopular, but since updated for the classic count of favorites.
