A few weeks ago I added my blog's feed to my Facebook Notes so it would automatically import each posting into Facebook's Notes application. It's easy to do, and it makes it convenient for friends who never leave the confines of Facebook to see what I'm up to.
I've only noticed a fews problems. One is that comments made on my blog aren't imported into Facebook and vice versa. It would be nice if Facebook would merge the two. Also if I embed a video in my blog post, Facebook won't include it in my Note. The last problem is speed: it sometimes takes several hours for my post to show up in Facebook. This is probably because it takes Blogger a while to update my feed and Facebook a while for it to check for changes.
Overall though I think this feature is a great idea.
Now that we can import our data into Facebook, how do we export our data out? I've just written a paper about this topic that is under review. Contact me if you'd like to know more about it.
