The 2 most fundamental features missing in Google+ (and I don’t know how else to send them feedback about this) that really really grind my gears are the lack of a +1 button and a “Share” link on the picture gallery mode.
I think that this has to be totally on purpose, I cannot believe that all the “geniuses” at Google haven’t felt the frustration of not being able to +1 or share a good picture from that view.
CEOs or Google+ project managers should be more involved in product experience. It’s cool how they are very data driven, but damn it guys, sit and use the product yourselves, or have you never used a social network before.
It’s just very hypocritical of Google to say that this is a service created to help people share, when sometimes it gets in your way of sharing at the very moment when you feel like sharing something with others.
And you wonder why they still haven’t opened the gates? It’s still far from ready to be used by the mainstream user.
What other fundamental features do you think are missing?
