The main effect of slow rollouts on me is that I never use the feature. It goes like this.
1. There's a service I use sporadically or used to use
2. They announce a new feature that might potentially mean I'll start using it again/more
3. I read the post, log in and realise I don't have access yet
4. I completely forget this ever happened.
Surely all the effort that goes into announcing these things is a bit wasted ?
What happened to the a nice "Labs" switch to opt into stuff that's new and a bit raw?
