Of all the social sharing, likes and hits services I've tried, Link Collider is my #1 fave. It's a very modern, well-developed cloud-based service that is simple to use and control from any web browser. It's a quite comprehensive 'All-In-One' SEO link building and social sharing platform with spintax support of all Titles and Description fields. It's elegantly designed and well implemented. Although there's many other competing Like Exchange and Share services, the user interface really sets it apart from others like AddMeFast or YouLikeHits. Link Collider's user interface is world-class SaaS programming and quite impressive!
