The idea behind the 500 friends was to pick and choose those that you found an interest in, but I don't see that happening enough. As for myself, I won't do that type of "netfriending" (oh no, I didn't!) either. Relationships are much more important to me.
I get all kinds of friends requests over on that OTHER social media site just for being attached to that individual anyway, I don't go hunting down friends on any network, I just put it out there and wait to see who takes an interest in what I have to say!
Thanks for reading my post! ;)
