Strangely enough, I've been in E+ several times the past week. I'm close but not there yet on status either. I selected seats for most of my flights, I'd have to go look but I think I selected stuff that ended up being in E+. I got there on standby once, too, on a flight that was mostly empty.

Several times I was in E- I noticed that it was practically empty at the front but packed in like cattle in the rest of the cabin. On one I asked about it and apparently a lot of folks ticketed in E+ had bolted to another flight.
