Spreading to thin

This blog is actually a part of my education.
I find this very facinating, and I more than happy to see, that even the higher academic world has opened their eyes to the many possibilities that the web offers.

There is just one tiny thing that leaves me hestitant, and that is the fear of spreading my attention to wide. Now, we do have the option to just delete our pages after the assignment is done, but as most veteranes of the net knows, it is not as simply as that. Many social pages, such as Facebook, does not allow a user to remove them selves completly, many of the personal tidbits you have given, will leave a bright trail of your past. As they say, nothing on the internet is forgotten. As the case of Thelma Arnold shows: http://www.nytimes.com/2006/08/09/technology/09aol.html?ei=5090&en=f6f61949c6da4d38&ex=1312776000&partner=rssuserland&emc=rss&pagewanted=all
The only real way to stay in control, is to control what you reveal, as it is impossible in these day to keep a complete secure private life, if you want to use the internet, or just to move around in the world.
Now, you don't need to do as Hasan M. Elahi, and reveal every move you make: http://en.wikipedia.org/wiki/Hasan_M._Elahi
But you can to some extent control what you show the world,
And in the end, that is why I am hestitant with joining certain pages. Since I am already a user of several social internet societies, I prefer not to spread to thin, so that I to some extent, always will have some idea of the fingerprints I leave.

For those interested, the author David Brin has written a book, "The Transparent Society: Will Technology Force Us to Choose Between Privacy and Freedom?"http://www.davidbrin.com/transparent.htm#ts about the problem.
