I like anything that allows me to connect with other sites of similar interests and have already discovered sites that I will be tagging once I set up a Delicious account from my home computer. Why try and re-invent the wheel when it seems like others have already done the work for me and I just need to link in. I am a little bit concerned about material that may compromise my computer, which has started to run very slowly and on running a scan has detected a number of ??????????? and deleted them.
