I liked the pre-Challenge Twitter video.
I was thinking Ed might want to talk about blocking people or what to do when people "follow" you that you may not want to have as a "follower". A lot of them are not, er, family friendly.
I was also wondering about the concept of only keeping a small group of "follows" and "followers". I see so many people with tens of thousands of of follows and followers and I wonder what the concept is. Wouldn't it be better to have a gazillion people to tweet a message out to?
I wonder if I should set up a different (second) Twitter account specifically to start from scratch for the Challenge and Ed's instructions on how to use Twitter for maximum advantage??
Just some "top of mind" thoughts after I watched the video.
