One thing I missed after switching my blog from blogger.com to wordpress.com was the ability to follow up on comments, see what others were saying and start a conversation from an entry. Blogger had the feature of having all future comments emailed to you. So, if I comment on Sarah’s blog, I would get to see what everyone else says, too. If I wanted to comment on a comment, I could link right back to the comment page. I missed that. Now WordPress is doing it, too! Way to go, techy people.
Here’s the article on it: http://en.blog.wordpress.com/2009/01/09/subscribe-to-comments/
