I must admit Google+’s user interface is clean and very user friendly. But that is what we should expect from a company which has deep pockets and some of the best usability labs at its service.
I think the era of “proper” interactivity has begun as far as user interfaces are concerned and Google+ is a great example of it. But what probably took Google months to produce a guy who is Voloko as an alias has replicated it in under 24 hours. I am not sure where he works but rest assured he is going to be hired by a large company in the next few weeks. He kind of reminds me of the young student who created “Youtube Instant” within 24 hours of Google announcing Google Instant.
To cut the chase Voloko has created a Facebook application that mimicks Google Circles. You can find try it for yourself at http://www.circlehack.com.
Circle Hack is open source and can be found here.
Here is a screenshot of my Facebook friends on Circle Hack.
