Just a couple of days ago, NTEN member and Social Media for Nonprofits expert Beth Kanter kicked off a great discussion about how NOT to use Twitter for your organization.

The key takeaways are:

• don't use Twitter as a blowhorn for your canned PR;
• don't think of Twittees as a captive audience;

and, everyone's favorite:

• don't Twitter without love.

I was really moved today to see one cause doing everything right with Twitter: the Frozen Peas Friday campaign from the Frozen Pea Fund.

Here's how it's working:

> It's personal. It's about one person's experience with breast cancer (and it involves frozen peas, of course).

> It's simple: update your Twitter avatar to include a pea-related image.

> It's time-sensitive. One day.

> It's backed up. There's a real and immediate cause with a clear explanation about where the donations go.

Here are some places you can find out more about this cause and this campaign.

I look forward to hearing more about how this goes.
