Thing #7 Wikki

So, a Wikki is a site that can be edited by anyone. Very interesting..But I have to ask some questions about this: Such as, If anyone can edit the site, how do you know that the information you are getting is accurate? I visited a library Wikki site from St. Joseph MI. On it was a link to geneology. I went on and printed up an ancestral chart. I think it would be great fun to do some geneology, although one of my cousins on my mom's side has already done quite an extensive dig about 10 years ago. Maybe I can do my dad's side.
