Writing about web page http://www.facebook.com
I'm sure everyone is already a member of some sort of online community for keeping in touch with your friends. However, I will strongly encourage everyone to join facebook . Amongst other things, your profile is highly customizable and searchable. If you are trying to find someone you met in the union, for example, a single piece of data is needed to find them on facebook — first name, last name, course, living arrangements, general interests… you get the picture (of course, knowing what they look like is also a prerequisite, and indeed worse comes to worse, knowing what they look like can just about be sufficient to find them!).
It also allows others to "tag" photos of you, so if someone else were to upload pictures of you and they tagged them, they can link straight off your profile (unless you choose otherwise), without you doing a thing.
There are many other reasons to join facebook, but why not find out for yourself? I urge everyone to sign up, so get facebook'ing!
