Blogger adds comment email notification
For example, Google has just added the ability to subscribe to post comments via email. Up until now, if you left a comment on a blog post and wanted to keep up on the conversation, you had to keep checking back with the page. While this might seem great if you're trying to generate more traffic for your site, the truth is most people will forget they ever left a comment and move on.
So it's great to see Google add this feature to Blogger. On the other hand, you can only subscribe to comments if you have a Google account. No Gmail? No e-mail notification for you.
