This would be my primary point
Relevant: the book linked in your thread "
The Psychology of Cyberspace"
It is merely an extension of self, psychologically anyway. 'In real life' one can not always meet all of one's needs, and perhaps one turns to an (social?) online community to seek to meet those needs.
With that being said, I don't use it myself.
Interesting to note is the ...140? (I think it was), character limit, thus preventing anyone from sharing a "tl;dr," perhaps they are quick memes, or thoughts, expressed in an online public atmosphere, and can there be "judged" or simply seen by many others.
Regarding "benefits," I'm not sure of the actual benefits other then mentioned above, but for *some* it may be seen as networking, a useful tool in today's atmosphere.
-Also the "trending," feature *may* be useful to some for networking and keeping up on the *current.*
Cons include constant updates/necessary to refresh to check for for the updates...almost *seems* neurotic to me...akin to hitting the INTPf "new posts" button too much...or refreshing your e-mail...or anything of the sort(checking the fridge over and over).
