I must not be the target audience for this kind of thing, but I really don't get it. The few times I've opened HN today I've seen this at the top, and the number of points has been higher. I've opened it 3 times, and clicked the button, and some other icons showed up below. The first time I didn't open even bother to mouse over the icons, so I didn't know you'd be buying things. I closed before I got to 50 stimulations. The second time, I did hover over the icons showing up, and clicked a couple, and nothing seemed to happen other than spending stimulation, so I closed before 100. I just did this a third time as it's now over 1200 points, and I really just don't understand what is going on. What am I missing?
