The Web can be accessed very rapidly and that can be both a delight and a problem. In an age of point and click you can be up and running in no time, e.g. this site. You can get there via desktop, laptop, mobile phone, TV and who knows what clever devices are yet to come?
Once there however, be “vewwy, vewwy, careful”. What you say, do, and type is all a matter of record and defines part of who you are and how you are known. Whether you are in an open source environment like this or the “walled gardens” of Facebook and Twitter, it is all about data driving data. Freedom of expression allows us a great venue on the Web, smell the roses (Ted talks, You Tube, all of the social media, etc.) but watch out for the thorns (scammers, spammers, data miners, and viruses). You might want to pause a moment before you hit that trigger.
Ted Berners-Lee, has written a great piece in the Scientific American, on where we are now and what are some of the important issues ahead. Check it out:
