Loved the concept! I have always felt that our profiles get restricted a lot to just the years and positions worked in. There is a lot more information that can be drawn from other social platforms.
Looking at it from the employer's point of view, this would provide a lot more complete and wider view of the candidate's performance and capability.
Though what I found a bit irritating in the product was I had to still fill in a lot more things, and spend time perfecting my CV making it more complete (despite of the information available in a proper format on my LinkedIn).
So a lot of work to be done! but keep up the good work! can go a long way.
A few questions to ponder? where do you plan to take this? is it just to make another LinkedIn? Any active measures planned to keep the user experience crisp like it is now?
