Few days ago I found out that I'm unable to open jekyll's default local URL (0.0.0.0:4000) in Chrome Canary (nightly version of Chrome). Instead, Chrome redirects me to the Google results for "0.0.0.0". I've alerted Chromium team about it ( http://crbug.com/428046 ) and I've learned that:

• 0.0.0.0 is a non-routable address
• they are going to push this change to stable
• I should use 127.0.0.1:4000 instead (and that it actually works)

My guess is that, when this change lands in stable Chrome, many people will be confused, as I was, about 0.0.0.0 being not accesible. To avoid that, it might be a good idea to replace default "Server address: http://0.0.0.0:4000/" with "Server address: http://localhost:4000".
