Off on a tangent: Are to elaborate? I've found Twitter extremely hard to use - people tweet and retweet so frequently, it always looks like a deluge of short, mostly meaningless, fluff. At least with Facebook, the longer bits of fluff are in a single post instead of spread aross and intermingled with other fluff.
But, maybe I'm doing it wrong? I really don't know. These days, I mostly stick to Instagram - it doesn't seem to have the negative impact on my psyche as either FB or Twitter.
