What does wikipedia do?
Wikipedia is an online repository of crowdsourced data which is edited by editors.
it is repository, users create on wikipedia servers.
what hakia is doing?
it is labeling the sites credible for its contents on a topic. Instead of storing all data on its server, it classify them and educate the users which site is worth referring. here also flagging the sites as credible is done by hakia editors as in wikipedia.
Can we think then hakia as distributed version of wikipedia?
Another product which comes close to hakia is Google scholar. Google scholar also helps us searching scholarly papers and it is distributed as well but Google do not have editorial control and its content source is not wide.
