I do not have a facebook page, so I have very little personal insight to add to this forum.
I did, however, pick up an interesting book at the airport a few weeks ago which discussed in-depth a side of facebook, social networking, email and internet search engines that I never considered. Yes, we all know the facts that usually get passed around: Internet is a tool–it can be used for good or for bad–it opens up tivot–it’s addictive–etc, etc, etc. I found it helpful to learn some of the technical and psycological aspects surrounding this debate. If you want, the book I read is “The Filter Bubble” by Eli Pariser. There are plenty more on this subject, not all of them negative if you’re looking for balanced veiw. Think of it as investment. Try to understand who is in charge of the company, what are thier goals and aims (there is no such thing as a free lunch), and what are the pros and cons of using thier website.
