Blog not appearing in Google

Questions related to wordpress.com should be asked in the wordpress.com forums, but your site appears to be displaying in Google fine.

For others with this problem, be sure to check WP Admin > Settings > Privacy to make sure search engines are not being blocked. If that setting is fine, Google can also sometimes take time to update their index for your site. You can check the index status of your site and get recommendation from Google using Google Webmaster Tools.
