I'm curious to know what people think about nofollow links, including the announcements that webmasters are free to use it to shape pagerank, are required to use it to designate advertising & encouraged to use it generously in web 2.0 type sites now that the dust has settled a bit.
Has the move (or some follow on effect from the move)...
..increased the quality of SERPS?
..reduced the prominence of sites containing user generated content in the SERPS?
..had the opposite effect?
I would imagine that the wide use of the nofollow on a whole range of user generated content sites inculding youtube wikipedia etc. actually means that pagerank cannot be used (by Google) in the way it once was. If you think about it, wikipedia is more or less what Google's pagerank concept had in mind when it was thought up. Credible (important, authoritative etc. ) authors publishing credible resources would lend credibility to other credible authors by referencing their work with a link in the way academics reference credible (important, authoritative etc. ) sources who's work they is important their own.
Wikipedia is authoritative and credible in the eyes of all those linking to it (giving it such prominence in SERPs) but this is not passed to other credible sources referenced in the articles.
