I'm a long time vim user, but I just learned recently that I can paste the yanked lines several times. I think most new users wouldn't know this.
Is it okay if I ask about this, and answer myself?
Ask the question and see what the actual community response is. It's possible it would get downvoted because people think it's too trivial or too much of an "artificial question," but it's also possible it wouldn't.
This site is in beta for a reason, and a big part of that reason is to help shape it, and as members of the private beta we can generally be considered to be among the more "invested" in the topic. As such you should not be afraid to take charge of the direction of the community. That's why you're here.
