You can use Zholink to save links that you don't want to lose or get lost in all the other articles that show up in your social feed (Facebook/Twitter/Google+) or RSS feed. You don't want to save everything in your browser bookmarks because that would just become too cluttered. Even then, your bookmarks are limited to that browser on that device or computer.
In the public lists, you can find new articles in the topics that you are interested in.
You see an interesting article headline or entertaining video that you just don't have time for right now, so you think to yourself that you'll read or watch it later. Then what happens? Life happens, you're busy at work, and the ongoing list of other distracting items in your social feed. You forget, but it's somewhere in the back of your mind, possibly keeping you up at night making you wonder "what was it that I really wanted to remember?" Zholink saves you from those nagging thoughts that keep you up at night. It saves your links so you can catch up on them later, without losing them in your social feed or email box.
