It seems to me that the most active use for G+ at the moment is as a broadcasting system, very much like Twitter. Maybe Google has envisioned this, maybe not. I admit I didn't. I thought Google would have done whatever it takes to promote more intimate and private communication among close friend circles.

But while G+ is arguably a better broadcasting system than Twitter, it is still broken. A tech celeb would love to consistently post tech stuffs, but while this activity satisfies his geeky followers, it would annoy his friends and families. And there is no way a tech celeb can manually add his followers into different circles.

I imagine if G+ fixes this problem, it will completely replace Twitter in no time at all.

One solution is to introduce a concept called Channels.

Suppose I follow DHH. The problem is DHH has a lot of interests, ranging from Ruby, entrepreneurship, to Forbes bashing (DHH fans bear it with me here). Now DHH doesn't know who among his followers cares about which of his interests, but he creates some Channels, namely "Ruby", "Entrepreneurship", "Forbes Bashing", etc anyway, so followers can filter themselves.

Now a Rails guy found DHH's G+ page. He would like to follow DHH, but he doesn't care so much about DHH's financial insight. Now that when he adds DHH to his "Follow" Circle, he can choose to pick some among many DHH's Channels and everyone is happy.

Finally, DHH's "public" posts are only visible to those who specifically added him to the "Follow" circle.
