Aidle maidle: One might ask, why do people feel YWN is a heter for lashon hara? Any forum in which people socialize and exchange views is a potential springboard for lashon hara; this is not a phenomenon unique to Facebook, or even to the internet. With Facebook or any other socializing agent, you must pay close attention to who your friends are and whether or not you really want a more personal window into their lives.
If one feels that one is spending too much time on Facebook, that’s an issue one must deal with on his own; it isn’t Facebook’s fault for being a stimulating website.
