Feedback Friday - Every Friday, a topic is posted on the Feedback Friday project page. The topic message could be, "For this Feedback Friday, we want to know what you think about the IRC channel."
Surveys - To take a more professional survey with more results, we could create a simple Surveymonkey page to use for elections and feedback. I know it's not hosted on the wiki, but it looks more clean.
This is under construction. Please feel free to add any other ideas.
These are just some ideas I had to help the wiki become more popular. Thanks! -Reeze
