As a twitter user, I absolutely HATE when people send me a direct message after I followed them. It really affects my general opinion of them, and I sometimes unfollow them right away. But, as an entrepreneur, I need to send traffic from Twitter to the AppStore, and I consider using this technique. A friendly welcome message with a little hint pointing to the AppStore. Question: Have you seen any difference on account growth when you activate auto DM message to new followers? Anyone has data on this?
