Go ahead and check it out, add the examples you know or have worked on yourself and help build a repository of Canadian leadership in the social media space that will benefit the industry.
I've even included a page for Canadian social media consultants to list themselves and link to their work if they like.
If you're not too comfortable with editing a wiki yourself and you have some ideas for tags or a better way to organize it, by all means let me know.
I also have to tip my hat to Dave Fleet who created the succesful Social Media Training wiki last year. Hopefully some of the people who got their start there have projects they can share on the new Web 2.0 Examples in Canada wiki.
