Just had a look at a quick video on Yahoo videos that explained social tagging in an easily understandable way. My first impression is to think I don't have the time to set this all up but then you think that it will help to organise the stuff you use and want to access quickly and easily but I am a little concerned about this sharing thing as not everyone has the same aims or intentions and maybe it allows other to enter my space a little more than I want them to. Clearly the whole digital thing requires a rethink and a reworking of how we want to function and global interchange means >4 billion other people to deal with! I had trouble dealing with the ones in my town!
