I have been looking at the difference between Lifestreaming / Lifecasting and Blogging for a while, and have just now launched a Lifestreaming Page on this blog, to investigate this further. Right now, Friendfeed is my favorite application for this purpose, btw - a great way to have everything in one place.
I need to find better code for some of these feeds, so if you have any suggestions please leave a comment here. In particular, I would like a better Friendfeed widget that displays the last 20+ messages from my feed, not just 5 or 6.
It seems to me like Lifecasting is more about just generating a public trail of notes, bookmarks, pictures, links and comments, while blogging is about real writing and more organized sharing (albeit often in morse code-like shortness). What do you think?
