I've been playing around with a tool called Backstitch, which is a news curation tool. There are plenty of them out there of course, but this is quite elegant. You can set up a free personal account and choose subjects that interest you. I chose to create a 'CILIP' collection, and Backstitch went away and found sites, social media resources and so on that I could add into my collection. When I was happy with what I had I could save it and share it.
What I particularly liked about this product was that I could then start searching in the content that it had found for me. It was quick and effective. The tiled results were a bit on the large blocky size for my liking, but that's a minor point. It also has filters for excluding material (including pornographic) which worked well.
If you're looking for a good tool to collect content for you, this is one that's worth trying!
