This article talks about twitter etiquette. If people follow you, what are your responsibilities to them?
Do you HAVE to follow? I have found that I only want to follow those people who are dead on topic for me with either SEO, SEM, Website Design, Blogging or simply those people that are within my state as I enjoy those connections as well. To just follow anyone and everyone that follows you created a huge waste of time for me, and even more things to look at and decide if they are worthy of my time. I am experimenting with having more than one Twitter “face”. I have my @yourwebchick profile for my business interests and @veryhappywife for the more girlie side of me that likes to learn and discuss things like gardening, photography, parenting semi adult, empty nesters, scrapbooking etc. I haven’t spent much time making connections on that one yet so I’ll let you know how my experiment goes.
