So who are the experts on certain topics online? The latest social media website Peer Index was created precisely to answer that question. Through the use of Twitter, you can find out who's starting specific topics and who the experts on those topics are. Whether it's suggestions for coffee shops in Paris, the best guitar pedals, or indie rock music, the site will try to help you find these trending ideas and the leading experts whose opinions are valued by their online peers. People can sign up on the site and create a profile that'll tell them how much people value their opinions and their online social capital in which they can compare themselves with others.
With sites such as AnyBodyOutThere and Tweet Psych, it's clear that hashtags on Twitter aren't enough to look for opinions on trending topics anymore. The constant need to find people to converse with on certain topics has taken over chat applications such as MSN. It's clear that social media will likely dominate almost all forms of communications in the future.
