One of the basic principles of what has recently been referred to as Web 2.0 (ie that part of the Web able to actively involve the community of reference) is the user participation in content creation through not only the uploading of data requirements, but also through strategies that make public the trends and tastes of the majority community, reflected in the final instance for emulation and spirit of belonging to a group, the community itself. But if this approach may be relatively manageable for the homogeneous type of data (photos, videos, physical objects, software) thorniest is for news and their careful selection. The editorial process leading to choose the news is in fact one of the most delicate and involves the consideration of many variables. Digg is a new project being tested since 2004 that applies a different principle: it allows users not only to report news perloppiù techniques, but also to vote for them, by publishing in visitatissima homepage only the most popular. Darwinian selection that follows is debatable, but undoubtedly the result of an effective and transparent process. The popularity of the site would encourage to continue the search, even if you manage to preserve the essence of individual choices, protecting the invasiveness of automatic support remains the most difficult challenge.
