I like how easy it was to set up my profile, create connections & find potential leads for me! It's almost too good at pulling information from LinkedIn so there are times when i have no idea what has been looked over/missed /etc - but they do make changes frequently which helps keep things fresh (at least somewhat).
The UI could use some work-it still feels very outdated compared even just last year or 2 ago.- not sure if this would be more of a preference than anything else however given their age as far back goes we haven't seen many other updates aside from improvements made specifically towards mobile users vs desktop versions. We recently switched our entire Sales team to using scoipy to help them reach out to prospects outside of networking events etc instead relying solely upon referrals & word of mouth only.
