Facebook added a "Notes" feature today that functions just like a weblog. Other friends networks have done this as well, but they often aren't used much because it would require the user to switch weblog hosts. Facebook fortunately has an import feature that allows users to continue posting on their usual blog. Entries are then automatically imported into the Facebook "Notes" feature. Furthermore, entries can be tagged on Facebook just like photos.
The advantage this has for me is that more people will undoubtedly read my entries. First there's a "Friends' Notes" feature, which shows all recent posts of a users friends. Second, my friends will be interested if they are attached to a post through tagging, which shows up, just like photo tagging, in the top left corner of a user's profile.
More people reading my post might also inspire me to post more...
I agree. I will be using it with my existing Wordpress blog for sure. Everyone needs the motivation to keep blogging.
