My personal favorite curation tool is Pinterest, which consists essentially of digital cork boards each containing clippings or "pins" of photos, videos, or links. The site is widely used and well-known as a cyber Elysium for recreational crafters, meme lovers, and anyone planning a dream wedding (real or not real). However, in my opinion, Pinterest is actually underutilized as a more professional curation tool. It is easy sign up (all you need is an email address), and building boards, adding pins, or finding followers are all just a few clicks away. The layout is minimalistic and visually appealing; every pin has a picture, and each board has a cover photo signifying the topic. This makes the process of gathering, categorizing, and sharing info easy. Users add captions or tag other users to increase searchability, and each pin can be shared via Facebook and Twitter and can even be embedded into another website or blog page. This has made searching and gathering info related to my Course Grind project much easier and less time consuming. I can search the thousands of boards already related to coffee, or just add my own link for reference later.
Pinterest also has a handy widget builder that can be added to images, websites, and blogs. The widget can be customized for a single pin, a board, or an entire profile. The size can be tailored as well. I sprung for the profile widget; check it out on the right sidebar of the blog page!
Whatever your preferred curation tool is, be careful to not go overboard! It's important to remember that the whole point of content curation is to gather relevant information and display it in a simple, logical, efficient way. Nevertheless, find a site that works for you, and have fun!
