Tweeting for the first time

So this week, we are tweeting. There are two parts to this and both distinctive. The 'posting' part is very nerve-wracking and I will always follow the suggested guideline, "You are what you tweet." Personally, it is not something I would do. I could see it being helpful in a library setting, if many of your clients are on Twitter. The second part is the 'following'.. how exciting! So many people and organizations to follow! But I could see this going against my personal philosophy of "Less is more." It seems a bit overwhelming with all that information coming at me. I would not be able to follow everything that is of interest to me, as I would have to sit in front of a screen all day long. It seems like a case of "More is less."
