I am an avid fan of Wikipedia. I use this tool for my research (with caution, of course), and read articles during my idle time. It’s very informative. Several years ago, I edited the wikipedia entry on Sorsogon province and completed the list of towns under it. I started editing the entry for Sorsogon City around 2004, mostly were typo error.
I find it fun sharing information to the public, of course, the sources of the information should be cited or can be modified if it has changed. Thus, Wikipedia is the best place to share such information.
