An overview of the wikitrust algorithms is here.
In a nutshell, new text is less likely to be reliable than stuff that has been subjected to a lot of peer review and survived.
Couple that with the matter of whether or not your edits tend to get reverted...
Ponca City writes: "After Liu Xiaobo was awarded the 2010 Nobel Peace Prize for his long and non-violent struggle for fundamental human rights in China, few voices in mainland Chinese media discussed Liu’s Nobel Prize. But Hu Yong, a media critic in Beijing, writes that China’s blogosphere and microblogs exploded after Liu was announced as the winner and a search of the hash tag “#Liuxiaobo” shows that relevant messages pop up hundreds of times per minute on Twitter. "Twitter has become a powerful tool for Chinese citizens as they increasingly play a role in reporting local news in their communities," writes Hu. "Chinese Twitter users lead the world, using it for everything from social resistance, civic investigation, and monitoring public opinion, to creating black satire, “organizing without organizations” in the Guangdong anti-incineration movement, and mailing postcards to prisoners of conscience." The Chinese Twittersphere has three prominent features writes Hu. First, as China’s rulers strengthen their censorship efforts, Twitter has become highly politicized. Second Twitter brings opinion leaders together around one virtual table, attracting a lot of “new public intellectuals” and “rights advocates,” as well as veterans of civil rights movements and exiled dissidents. Finally, Twitter has become the coordinating platform for many campaigns asserting citizens’ rights. "With the proliferation of Twitter clones in China, social movements in China are getting a long-term boost""

I thought, made using this plugin I could read Wikipedia articles about politicians without being misled by vandals, so I created Wiki Voter Guide which uses Project Vote Smart's API to look up Wikipedia articles about candidates by ZIP code. Turns out, most local races aren't covered in Wikipedia yet, but I'd like to know what Slashdot readers think about all of this. With the help of reputation systems can Wikipedia become a useful way to research political candidates or is politically motivated vandalism an insurmountable problem?

Users can generate lists of every edit to Wikipedia which has been made from a particular IP address range. The tool has already uncovered a number of interesting edits, such as one from the corporate offices of Diebold which removed large sections of content critical of their electronic voting machines. A Wired story provides more detail and Threat Level is running a contest to see who can come up with the most interesting Wikipedia spin job. I'll bet Slashdot readers know of some interesting IP address ranges to check."
