If you have a Tumblr account (they’re free!) you can subscribe by clicking the +Follow button up top. Project Neon updates will appear in your dashboard.
You can also read Project Neon in your favorite RSS reader (I like Google’s Reader and Reeder for iPhone).
Or you can receive updates by email from FeedBurner. Once you submit your address, look for an activation email in your inbox, or possibly in your junk or spam folder. Click the link, and you’re good to go.
