Segmentation from the portal

I can think of one feature that would help community founders enormously, now that multiple newsletters and comments are available.

In the list of subscribers, it is possible to add tags to categorise. The problem is that if it’s a subscriber you don’t know, who came here by search engine or recommendation, you don’t know how to categorise them. And so we don’t know how to communicate with them in a more appropriate way.

What would be a major asset would be a proposal for a category to be chosen when subscribing to the portal. This would help creators understand their audience and improve the link with them.

What do you think about this?

Has this already been proposed?
