I know it’s completely subjective, but I really prefer uniformity of Twitter’s design over what Google+ is doing. To me, Google+ is interesting, but at first glance it looks like chaos.
When you give people the ability to have different sized areas for things, I find that they tend to go bigger because YELLING gets you noticed more than whispering. What’s great about Twitter is that people can’t do that. It’s about the meaning of the content, not the size of it.
This is actually related to one of the reasons I preferred Facebook early on over MySpace. Facebook had a uniform design for profiles (and still does). MySpace let you do whatever the hell you wanted.
If you give a child crayons, he’s going to draw all over the walls. And there are way too many children on the Internet.
I would say that Twitter is far and away better than Google+ on this front. I say this for the same reasons that news radio is often better than television, and that black and white photographs so often communicate better than colour –– when you narrow the bandwidth, you focus the message.
The people I follow on Twitter –– many of whom I have become friends with –– excel at the medium because it’s a format that demands brevity and clarity. When the information hierarchy is all the same, the reader is forced to weigh up the value of the information herself.
