Dear Worldchanging Readers,

We experienced a system crash this morning and our Attention Philanthropy collection hit your RSS feeds (and our homepage) with a lot of broken links. Please accept our apologies (and thanks to those of you who emailed to let us know you were concerned).

The feature is now fixed. Click here to read it.

For those of you who read Worldchanging via RSS feed: you'll get each new Attention Philanthropy grant in your feed as we publish them throughout this week. But if you want to share the full list with others, please use the link to the feature on our site to ensure they get the most updated version.

Thanks for understanding, and thanks for reading!

Please note that comments will remain open for only 14 days after the article is posted. While previous comments will remain visible, attempts to post new comments after this period will fail. This helps stop comment spam, so your forebearance is appreciated.

The Worldchanging comments are meant to be used for further exploration and evaluation of the ideas covered in our posts. Please note that, while constructive disagreement is fine, insults and abuse are not, and will result in the comment being deleted and a likely ban from commenting. We will also delete at will and without warning comments we believe are designed to disrupt a conversation rather than contribute to it. In short, we'll kill troll posts.

Finally, please note that comments which simply repost copyrighted works or commercial messages will be summarily deleted.
