The majority of current research on reputation mechanisms has focused on the application of such mechanisms in online marketplaces. Increasingly, researchers are looking into other domains where such systems can play a useful role. Some examples include:
· Peer-to-peer networks 
· Wireless grids 
· Professional guilds 
In contrast to the above proposals, Jeff Ely presented a paper where he outlined an (abstract) setting in which publicly available reputational information ends up harming otherwise honest service providers . His paper shows that the development of reputation mechanisms may not be socially beneficial in all cases.
