We talk a lot around these parts about our philosophy of Share Then Like wherein your content should be so good your audience will share it with their audiences rather than simply Liking it.
A recent example we participated in was sponsored by the Teespring company to promote the efforts of the Immunity Project and their efforts to develop a free vaccine to end HIV and AIDS.
The Share Then Like philosophy was applied when Teespring asked visitors to the campaign page for the effort to send a tweet promoting the effort. The tweet only mentioned the Immunity Project. The first 150 audience members who sent the tweet were then sent one of the shirts for free, postage paid.
Due to the power of the campaign and the social audience behind it, another 1142 shirts were sold, at $19.99 each, raising $22,828.58 for the Immunity Project.
While we did not have anything professionally to do with this effort its good to see that everyone wins when Share Then Like is put into action.
