The long tail…and the shift to micro-niches…may change your target group. It may change into its own little eco-system of multiple target groups. So the way you communicate, dialogue and message with them may become more specific. And, with two-way communications (Web 2.0) you can also invite more involvement (what Huba & McConnell refer to as “The Participatory Economy”) from your target audiences and you can become closer to their exact preferences, wants and needs (as marketing is about serving these).

Also you can start creating more markets, instead of just serving them because there is so much room for innovation due to so many choices (the long tail is about more choice and more niches, no longer about audiences grouped by, say, age range). All told, communications become more dynamic and rich since we’re really homing in on preferences (so it’s now “psychographics” instead of “demographics”).

I think so mainly because you are dealing with a much smaller group, and have the chance/responsibility to deliver much more personlized messages.

Which are, in theory, far more relevant. And effective.
