This is what I alway told myself. "I have no problem with small spaces"
Until I went a day of cave exploring in the Ardennes. You are sent through a cave, without any light. At some points there are small beams of sun poking through holes, or at some there is a small ledlight indicating a step down/up Halfway you're going to reach an intersection, left for 'normal' right for adventure, we picked adventure ... This entailed a narrow pasthrough, barely wide enough for me, and a few climbs up and down. Your track is monitored, and you have max. 20 minutes before they come and get you, but still at some point I felt real anxiety of being stuck.
Since I KNOW I'm getting older, and admitting fear is nothing to be ashamed for ;)
When you follow the money, yes. Users who register'share' the as adrevenue. You need to have a lot of exposure and followers to get the check written. Guess who's getting more money ...
