The term "curation" appears to be on the rise lately in many web, iPhone and iPad applications emerging and mainstream blog articles being published such as “Why Content Curation is Here to Stay” and “Curators of the Real-Time Web: Distilling the chatter to relevant, actionable information” although this is not showing up too much yet on google trends.

User Generated Content (UGC) has become the "norm" in many web2.0 and post web2.0 applications where text, images, audio, video etc. is openly shared and licenced with licences such as Creative Commons or freely shared via the "embed" where legal reuse and repurposing rights and obligations can sometimes be difficult to ascertain due to that lack of an adopted content licence.

RSS is well established for sharing a "collection" of resources from a single source and OPML is gaining adoption for "collections" of resources from multiple sources. On the real-time-web front protocols such as PubSubHubbub allow the real-time publishing of feeds but the usefulness and relevance of these feeds appears to be sparking a new area of interest in web apps.

One aspect of "Web 3.0" could be seen as the "return of the expert" and the rise and validation of the "subject matter expert" where their curated "works" is seen as holding value over and above other people and their collections due to them having more contextual social capital or "whuffie".
