twitter or facebook? why?

[Bryan]

It is a purely a matter of choice and what you want in a social networking website. Personally, I prefer Twitter over Facebook because there is some serious invasion of privacy on Facebook even with all of the privacy settings tweaked. I do not have to worry about people snooping on my relationship status, friends, etc. etc. on Twitter since it does not exist in the first place. As I said, it is a personal choice and while Facebook might have its own benefits, I'd rather choose to be an active Twitter person than a Facebook addict.

In the case of activities or interests, they could be equally rewarding. Here is an example of how one group can promote its activities across both platforms.
