OK, not total computer illiterate but no cell phone, no cable, no internet at home, never texted, think, speak, write the King's English
. I've eaten hash, smoked hash, hashed things out, even marched across hash marks on a football field but can someone give me the short bus version of what a hash tag is or what its used for since everyone but me seems to automatically know what one is. Some sort of marker or sticky thing to keep it somewhere or make you see it?
