Who doesn't know wiki!
A great system for people to share information. This is great for websites and communities, but has downsides when you want to make one big information source.
Since as you can read on many news sites and/or blogs the information isn't always correct. In fact many propaganda is added to our beloved wiki.
Danny Wool (former) member of the wikipedia foundation and long time contributer started Veropedia.
To quote from the Veropedia.com website:
"Veropedia is a collaborative effort by a group of Wikipedians to collect the best of Wikipedia's content, clean it up, vet it, and save it for all time. These articles are stable and cannot be edited, The result is a quality stable version that can be trusted by students, teachers, and anyone else who is looking for top-notch, reliable information."
All I can add is that I truly hope that it becomes a success as much as wikipedia is today.
