I’ve just taken a quick look at friendfeed.com – it’s basically a lifestream service, where people can aggregate and publish their web-lives. It’s done rather nicely – enabling you to quickly create your own lifestream from various feeds (here’s mine) and not too different in look to the lifestream I quickly hacked together with pipes – but done way better and on a grand scale! You can also track friends’ feeds easily too, making it a much more two-way tool than others out there – say Tumblr, for example, which publishes your combined feeds. There’s definitely a need for this – with the whole micro-blogging/twitter/lifestream thing, it is useful to show this data in one place and provides an excellent way for potential stalkers to gather all their up-to-the-minute information on a particular target in one easily digestible feed 😉
