To celebrate its five-year anniversary, Mashable is producing a series of posts on developments in social media. The latest looks at the impact of social networking on news consumption and the idea that social networks have become personal news wires.

Following a discussion of online “friends” evolving into our news editors, writer Vadim Lavrusik rounds-up some interesting ideas about ways to measure source credibility in the future for greater transparency online.

Though news is increasingly social and user-generated, the persistent fear is one of credibility and a flaw in measuring a curator’s knowledge on or interest in a topic. This problem could be improved by enabling users to develop more targeted news feeds on personalized topics of interest, but also by identifying specific sources and curators of information as more or less credible than others.

This could also include sifting sources based on whether they are eye-witness to an event or are experts on the topic, both of which add value in their own way, he said. Such a model could then help establish a credibility index among users as sources, helping consumers better decide what information is credible.
