Aaron is calling out male bloggers to put up a link to the Breast Cancer site for the rest of October. Just by doing this, you can help fund mammograms:
Your click on the "Fund Free Mammograms" button helps fund free mammograms, paid for by site sponsors and provided through the efforts of the non-profit National Breast Cancer Foundation to low-income, inner-city and minority women, whose awareness of breast cancer and opportunity for help is often limited.
For the skeptics out there raising there hands in protest, it's already been de-Snoped. It's for real.
It's one of those rare things in the blogosphere that unites rather than divides, so just do it. Would it really hurt to have a big pink button on your site for two weeks, considering what its for? No.
