Wendy, any time. I do look though because there were a couple of times they said someone stopped following me, but when I looked at them on Twitter, they were still following me. Not perfect, but makes it easier.
Abbie - LOL still trying to figure out why you follow me? (joke) I use that program because there are some folks who followed me first, and I followed back because they were also an artist of some sort - visual, musical, etc - then two or three days later, they unfollowed me! I'm like WTF, over? Why did you follow me to begin with? I don't like people who do that. There's a number of folks that I follow that don't follow me back. I followed them for the reason you mentioned, because if something that I have an interest in. :-) I've found it to be a great networking too. And if someone wants more exposure and visibility, this is one easy and non-aggravating way to do it.
