With memosnag you can create notes, but most of all you can save pretty much anything you find online with a simple click. Images, YouTube Videos, text, webpages, and links. Everything is saved in the cloud and can be accessed across devices through your personal Gallery. From there you can create collections to organize your content. The drag-drop feature on web is very handy for this. You can also share your collections with other users, invite friends, make collections public or keep them private.
Memosnag is a startup, so it's still pretty simple and unsophisticated. In addition to the web app (that works great also on mobile web), there is also an iPhone app and Android will be available later this year.

Pros
Pro Now available for Android
Memosnag just released (Oct. 2016) the Android app, and it's really a great app. Saving content from Chrome and other browsers is very simple, you can save content form many other apps (CNN, Reuters, YouTube and a bunch other ones), and also images. They are saved in your gallery, and it looks awesome. Organizing your saves in collections is very simple.
