G+ is so much better than facebook. Unlike facebook, It has no ads (and coming from a company that relies heavily on ads!) no arbitrary user deletions, no strict limits. Moreover, it has so many features that are absent from facebook and a much better page layout.
My suggestions for the G+ of the future are these: 1) HD Hangouts with more than 20 people on them. Optionally 3D HD Hangouts. Private (and not only public!) recording of these hangouts. Better effects that can alter voice and not only our images 2) Word processing capabilities when posting or editing text 3) Video processing capabilities at least on par or better than youtube and deeper integration of youtube with G+ 4) Different styles of appearance like those that exist on Gmail 5) Subcircles. Useful if you want to categorize a circle inside a larger circle and treat it differently 6)Promotion of open source, open hardware and open science through a distinct label. (like G+ Open) 7)Resurrection of some defunct Google services like Google reader through G+ in a clever way 8)Tools for programmers and integration with Google code (also in a clever way that will not frighten the average non programmer user) 9) A blog label that will import and export blogging posts from wordpress or blogspot 10)Smart statistics of usage based on many factors (time, ways of use, kinds of interactions etc), symbolic rewards and a straightforward diary template 11) Internal tabs that will enhance the functionality of G+ (Right now tabs exist only when you want to see your different circles. Just expand this functionality throughout the whole G+) 12) Deeper customization in every level to the point of personalization. 13) Integration with Google.org and raising the social responsibility towards the world social problems (poverty, wars, state oppression, pollution, waste, blind violence, racism, sexism etc)
Anyway, G+ is evolving rapidly and nicely and I am looking forward for the new changes that you will announce today!
I hope that someday G+ will annihilate facebook and unlike facebook it will make world a better place for all...
