I’ve been pondering (rather slowly) turning The Philippine Presidency Project into a Wiki (though not freely editable for the near term) and started a kind of public scratch pad with a Wiki on the 2007 Elections.
Apparently one useful rule for Wikis is, if one exists covering your area of interest, instead of creating yet another wiki that might die, simply go and identify the most relevant wiki already online, and add to it. Here are some pretty nifty ones that I didn’t know about before:
JurisPedia which covers the law, and legal and political sciences. Adding an entry on “constructive resignation” would be useful here, no?
If you have a primary source, why not consider adding it to WikiSource? Some people have put the Absentee Voting Bill, as well as the statement of the Hyatt 10, the President’s February, 2006 State of Emergency Proclamation on it. There are also the documents on the surrender of Japan, for example.
An exciting one is Wikocracy, where people can post a law or even a constitution, and ask others to revise it. I recall discussing a similar exercise with some readers. Perhaps this wiki is the place to do it (an anti-terrorism law proposal, or revisions to the Philippine Constitution).
Were you part of history? Share your eyewitness accounts with the world. MemoryArchive is a wiki precisely for that purpose. See this account by a veteran describing his experiences in retaking Corregidor in 1945.
