I've had three times where I bumped into people who used information that I had put onto SP. The first time it was while hiking in the area. I met a couple guys out there and one of them commented that there was some "great information about the area" on a website called SummitPost. I laughed and told him I was intimately familiar with it--since it was a page I did a great deal of work on (don't own it, however). The other two times it was separate incidents in which folks later commented to me that they had been planning a trip and they came across my name on SP pages. They appreciated the information that was provided--it made planning their own trips a lot easier. I like votes, but those three incidents are worth a lot more to me.
