Twitter+Etiquettte+(twitiquette?)

= It is considered common courtesy to "follow back" when people follow you, but some are spammers. They just want you to follow them. Or some might not be spammers, but if they don't seem to post anything that would be of interest to you (or is worth your time), don't follow them. =

= = = Some people won't follow you if you "protect" your tweets. I protected mine for many months, but a presentation by Kathy Schrock convinced me I should make mine public. That did make a positive difference. I still have my notifications set so that I know when someone new is following me. (and I block some of them) =
