The newest thing I have learned about Wikipedia is that users can create bots to crawl through articles to fix up common mistakes. These include potential vandalism, date format, basic spelling, etc. I looked into it a little bit, but I think it's way too much work (read: programming) to create my own bot. It seems relatively uncommon, as there are only 668 bots for all 3.5 million English articles. It's interesting (but not completely surprising) that these exist, but the only way to know that the bots are editing are to view the page's history
In my preparation for the presentation tomorrow, I also found out that in order to find out more about Wikipedia-related subjects (users, bots, etc.) you can search for WP:Users or WP:Bots. By prefixing your search with either "Wikipedia:" or "WP:" it looks for the pages directly tied to wikipedia. This was very useful to find some stats (WP:Stats) and general information for tomorrow (WP:About).
On that note, here are my questions for tomorrow:
Is it still collective intelligence if only a few users edit an article?
Why are most people only consumers of Wikipedia, and not also editors?
