Summarization is one strategy to use against InformationOverload.
Find a way to summarize information such that you don't get bogged down with similar news, and that learn about important news. Newsmap tries to present the Google News feed in a treemap in order to show how many news sources (an aproximation for importance) reported on a certain subject (group similar news).

Something similar to Newsmap for goxogle but for wikilandia would be imagineable if we had contents reflected on topic-nodes all over.
