login with google/facebook/linkedIn Account
One of the thing that prevent me and my family using the service is the fact that they need to create an account. Some people (who says the old ones ! :) ) tends to refuse creating account everywhere. It gives them the impression of security breach and it becomes difficult to remember every passwords.
So if they could sign in with their already existing facebook account or anything else it would be easier.
By the way I just saw that here on the forum we can log with facebook ang google whereas I did not see it on the main site.
