Cue overly obvious "ain't nobody got time for that meme", lol.
But seriously, I understand your points, and they're all very true, but really, as I get older, I have neither the will, stamina, or desire - and in fact, not even the attention span - to run accounts on multiple meme sites. I'm a one-woman guy and a one-website memer.
In general I just like to piss and moan with like-minded people, just to help get it off my chest. Usually a simple "yeah, I hear ya bud" does wonders for me.
