Personalisation: the effective way to communicate

As a new user of Twitter, I spent some time looking at some accounts and selected few to follow. Some of them have a six digit number of followers. I thought they might be worth following. Some of them followed me back. I appreciated that and I was grateful. I decide to send a message to express my gratitude. I was surprised; the answers were really nothing close to what I thought. I was disappointed. The answers were mainly ads, and links to direct me toward some web pages. I do value each person work and I do understand how valuable for them the time they spend writing but if my presence on the web is only considered as a potential client or a source of revenue, I would appreciate bing approached differently. Maybe my expectation are high but hang on it is the person who is speaking here not the marker and I believe that we are in a world in which all clients got higher expectations that we should do much more to meet them.
