It has nothing to do with features, appearance or privacy. And I’m certainly not opposed to the type of social networking it entails. Rather, it’s all about laziness.
@marknca put it quite succinctly on twitter:
I don’t really want my social networking to feel like effort, and that’s what’s happening right now. It’s taking time to map twitter handles to real names, and to figure out if I want to share baby pictures of my kids with this person I met at a conference but not this other person. And as usual, I’m probably over-thinking it.
I’m normally a reasonably early adopter of digital tools, but I’m dragging my feet on this one. I was happy using Twitter for primarily professional purposes and Facebook for primarily personal uses. Assuming Google+ doesn’t fizzle like Wave or Buzz I’m sure I’ll get there in the end, but this one make take me a while.
