Hi Deborah,

Interesting list. As you know, several of these are high on my "what not to do" list as well. But I have to disagree about Follow Friday. While too many people use it to broadcast lists, it can be worthwhile. 

Done right, Follow Friday is a good way to both thank someone who you find valuable AND point people to others that might be worth checking out. I'd add that this is even more important now that seeing @ replies are limited to conversations where you're already following both people.
