Difference between content curation and link spraying

I’ve always been concerned about how little time I have to really review web 2.0 tools, websites and such like, let alone implement good ideas into my teacher librarian practice yet other people seem to be able to recommend masses of sites, apps, tools and the like. Where do they find the time? Consequently I was really pleased to come across this website -The difference between content curation and link spraying. I’m obviously on the side of content curation – well after all I am a teacher librarian so it all makes lots of sense to me.
