....but if all the planned features start running from the Nxt client then you automatically have a social network....alaises, msg, social exchanges, forum etc.
Think it's about the degree to which the NXT client (or plugins I guess?) can integrate and present these features to the user. Like, suppose all these features are implemented. Would be great if you could filter e.g. forum posts from [Friends] in threads (or personal page, if such a feature is implemented) tagged with topic from [Topiclist], trade offers from [Trusted Friends] for items in [Itemlist] and currency in [Currencylist], have them presented to you somewhere convenient, and get linked to the relevant forum thread/marketplace, all from the same app. Not so great if you have to visit each place separately to keep up with what your friends are doing at these places.
I think the more a third party can provide such features on top of the NXT client, the more they will be able to monetize.
