My digital footprint keeps on growing but my life doesn't really have room for it all. Almost every week now I join up with some new social network or web service. My portfolio of user names and passwords is also becoming frighteningly impressive and it's getting harder to keep them all in order (just waiting for someone to tip me off on a web service that organises even that for me!). It's hard to find secure passwords that you have any chance of remembering. I remember reading several years ago that the most common password is "password" but many sites won't accept simple solutions like that. If you try to enter a simple password you get told that it's too easy and that you really should use a mixture of letters and numbers and preferably lower and upper case letters.
There are now several tools available to help people who are OD-ing on social software. If you've got multiple blogs, wikis everywhere and are a member of far too many networks and communities you can now gather everything in one place and showcase your entire repertoire at one address. A new contender in this category is called Popego and it even promises to deliver related content and contacts to you once you've registered all your other networks there (I've previously mentioned FriendFeed which is a similar service). I got in there and have tried to register my various identities but keep getting told that my user name doesn't exist. In some cases I can't even remember what my user name is. I like the idea and it could be fun if I can only remember who I am.
I am however quite enthusiastic about Last.fm, a social network based for sharing music. It tracks everything you play on your iPod and computer and tells your friends what you're listening to. It also enables you to compile your own "radio channel" so that your friends can hear the music you like. Whenever you listen to a track you get information about the artist via a wiki (you can add details to the wiki of course) and you can also download tracks and albums via Amazon.
