The original reason behind why I created SeeLink was to share important links with friends and family. SeeLink makes your links shareable, searchable, and easily readable (as it displays each link in the form of a card with a title, description, and image). It also allows you to write text around the links using a tag, and has a ton of link specific features that make it easier to share links. These include creating specific boards through which you can add specific links to share with specific people. I think these are the main advantages that SeeLink has over something like IM clients. Let me know if you have any further questions!
