In my Time to Tweak Your Twitter Strategy article, I asked what strategy people were following for thanking people when they tweeted or re-tweeted your blog posts. I had read a couple of articles where bloggers had touted the value of not thanking them. Instead of thanking them, the suggestion was to re-tweet something of theirs. There was a lively discussion in the comment section but what surprised me the most was the number of people who send direct messages on Twitter. So, my question to you is, how do you feel about Twitter direct messages?
