Increased connectivity both in the information and social domain, suggests Steve Wheeler leads to an online learning landscape where context and community are key. We have streams of information that we have compartmentalised into Twitter lists or Pinterest boards that are designed around our interests. Whilst this helps limit noise in terms of articles and resources that we don't find useful, it can result in an information bubble where we aren't being exposed to alternative arguments or opinion. Many web resources now facilitate forms of social curation, facilitating interaction around these resources. Examples of this are group Pinterest boards or collaborative documents such as Google Docs/Sheets, and (as previously mentioned) list.ly where you can up/down vote add and comment on items within the list. Tools like Gibbon facilitate design of your own curriculum, curated around your interests.
Personally, I've also started using the blog as a form of curation and where there are reference points, I've added links. There is such a huge amount of knowledge available on the web, we need curation tools and curators to funnel the information and we need social interaction to facilitate critical engagement.
