Sites are getting into it.

Recently, I was on wayn.com (Where Are You Now) site, which is a travel/travel blog site. I noticed on it that they have added an “issues or cause” section to the site.

…Next month we will be launching a new Make_A_Difference campaign chosen by our members. You can currently vote for the issue you most care about and the one which has the most member votes will be turned into a global campaign from which we will publish our member input from a more detailed poll. Take the opportunity to support your issue now!

This is an example of how any site can add interactive elements to their website AND do it for a good cause.
