I am by no means an experienced micoblogger/lifestreaming (let alone blogger..).
That said, I heart Soup.io. Easy to use, no sign-up to get started, user experience is dead simple and intuitive. Though it’s a crowded space, it’s a service worth checking out. Really like how easy it is to share and repost within Soup.io, facebook, twitter, etc..
My soup can be found at Justin’s Soup.
