Dear readers of Electronic Markets, We are happy to present the first general research issue in 2012. It includes five contributions which investigate various aspects in customer interaction, an area receiving increased attention with the upcoming Social Media and mobile technologies. In fact, we observe that these innovations shape the picture of the ‘empowered’ customer who has the opportunity to obtain information from a variety of sources via multiple channels.

They report that the overall mood has a positive influence on purchase decisions and provide some insights on how it may be influenced. A major factor is solutions which increase the feeling of social presence and create a “warm” environment, such as virtual communities, forums or chats. Further factors reported in the paper are individualization and customization of offerings and communication. An established means for customers to express their opinion are rating systems.
