Widely-respected social media maven, Beth Kanter has become personally involved in the issue of hunger. She offers some very good tactical advice in this blog post, also asking for examples of hunger relief groups using social media to advance the cause (BTW, if you're a non-profit, you really need to have Beth's blog in your RSS feed).
Beth will be a featured presenter at the upcoming Share Our Strength Conference of Leaders, in DC, in October. If you're planning on attending what is usually an excellent conference, this will be a must-attend event.
A tip of the hat to Beth for her involvement in this issue (also, many thanks for her support of both the Austin and Bay Area comments-for-food efforts).
