Write4net is an interesting publishing tool, that describes itself as a service to publish articles. The service facilitates the instant publishing of articles without the need of an own blog or website. But the features are going beyond just publishing and coming closely to make the service a complete social network. By publishing an article the service automaticly generates a profile and presence for the writer with a couple of networking facilities based on Twitter account data. This presence is completely equipped with an own newsfeed, article sharing facilities and comment functions. Too, published articles are immediately posted to Twitter.
Here is an example of a presence, which has been generated by a trial making an introduction to the service:
This all happens by using Twitter account data to publish articles based on the Twitter API. So one may either think about the service being a social network itself or a new Twitter application. At all it is a most useful publishing tool.
