OneWebDay, an "Earth Day for the Internet," kicks off today. Celebrate by enjoying the creativity the Internet enables. Post a blog entry or a video; update a Wikipedia entry; remix a music track; learn something new. Tag entries with "onewebday" to let others find them.

In New York, there's also an offline celebration, New York - Wiki
