Personally, I hate automatic DMs. In case you are unaware of what I am talking about, an auto Direct Message on Twitter could be the email you receive from choosing to following someone on Twitter. One of my twiiter accounts received over 170 DMs year to date. Of that 170, I've received maybe 7 DMs that were interesting enough to encourage me to engage the person who auto DM me to begin with. Personally I liked @Nik_Nik auto DM which was a video of what I was getting into as a result of following her. Funny, unexpected and different from the traditional: "Nice tweeting with you. Looking forward to your tweets."
