The following scripts change the site significantly:

CRAIGSLIST

Craigslist Comprehensive Clean-Up

This is a full-site user style that aims to pretty up all sections of Craigslist. 
* Default font is changed from the browser-default of Times New Roman to Helvetica Neue/Arial.
* Extra spacing and a greater leading has been added for better legibility.
* Front landing pages have been tidied up and is now presented in three columns. All those tiny blocks are gone.
* Perhaps the biggest difference is the Table-of-Contents and Listing pages are now only 700px wide. This setting greatly improves legibility for long blocks of text.

IGOOGLE SCRIPTS

iGoogle: Compact & Transparent top bar

This style removes a TON of padding and margins, allowing for more feeds and gadgets on your iGoogle homepage without scrolling. It reduces all headers and RSS links to be single-line only. It also removes the header and footer spacing. As a bonus, this style removes some of the header image, and makes the white bar at the top transparent. Because the text is white, it works best on dark themes.

New iGoogle – Hide The Sidebar, etc.

This style hides the side bar and a couple other annoying things in the new iGoogle.
http://userstyles.org/styles/11373

GMAIL SCRIPTS

http://userstyles.org/styles/19999

Gmail Ads-block and Full-width

This style removes ads and widens the message area of Gmail.
http://userstyles.org/styles/22317

Minimize Labels in Gmail

This style minimizes all labels in gmail to look only like a box. If you mouseover each box, it will expand to show you the name of the label. This greatly increases the amount of space for text in your inbox, especially for emails with many tags on them. The ad sidebar is shrunk down to save space, hovering over it will give you access to the options such as print, new document, and new window.

GOOGLE DOCS SCRIPT

Google Docs – Mac OS X Leopard Theme

Transform Google Docs into a Mac OS X Leopard app. The buttons are modeled after the leopard Finder toolbar buttons, as are the toolbars. All menus and contextual (right-click) menus are themed to look like the native Mac OS X menus. This theme also styles Google Docs’ DHTML windows to match the actual window chrome from OS X, adding shadows, status bars, lighting and cursor modifications to complete the effect – the two types of windows should look identical after enabling this theme.

*note that this doesn’t restyle Google News Archive pages, because the html for the archive is oddly not marked-up with any ids or classes.
http://userstyles.org/styles/20830
