SearchSuite is a userscript that provides user control over search results: it can strip them down to a single-spaced list, sort, and more. Most of its features are presented as menu item toggles to turn each feature on/off. Each menu-item-controlled feature works on the output of all the others, in both their on and off states. Feedback and feature suggestions welcome.

...it is inappropriate to cite Wikipedia as a source, because it is updated in real time. So from the time you cite a Wikipedia page to the time another person looks up your citation, the page may have changed. Citations are usually only applicable to static publications that do not change once they are published. Wikipedia is not a static publication, it is dynamic!—it changes every minute. In this sense, Wikipedia is not a reliable citable source.
How reliable is Wikipedia as a general resource? Very reliable. Most of the content on Wikipedia is accurate, and many subjects are updated faster than the news. But, Wikipedia is subject to being edited by almost anyone and any time, and the edits may be biased, out of date, incorrect, or malicious (vandalism). Therefore, it is advisable to double-check what you learn in Wikipedia against other sources.
Keep in mind that many volunteers monitor Wikipedia for errors. Since there are so many people reading the articles and monitoring contributions using the Recent Changes page, and using watchlists, incorrect information is usually spotted and corrected quickly.
Some argue that new errors are also introduced all the time, so that the overall accuracy rate is not really improving. Nevertheless, by encouraging people to help with correcting articles, validating content, and providing useful references, errors will eventually be greatly reduced.
The more accurate Wikipedia becomes, the more it attracts additional contributors. It is a self-reinforcing cycle!
