Well, I can only speak from my own experiences, but just last night I happened upon a discovery. Let me share a little bit of the story:
There I was was, out in the middle of nowhere, jumping, honking, scooping, FSS-scanning, mapping worlds that caught my particular attention. Sometimes it was because that world had some geological or biological point of interest. Other times just because the planet was interesting to me in some way - an ammonia world of unusual coloration, a gas giant with interestingly contrasting rings, a water world with a massive ice-cap, or a high metal world that could pass itself off as an Earth-like world. In one particular system I mapped a peculiar colored water world. Right next to it was another world that caught my eye. The little sliver of it that was illuminated showed this to be one of those atmospheric worlds that resemble some kind of odd candy, with ice caps and a smooth appearance. What happened next though, as I came around the planet, intending to grab a screen-shot, well, it's the stuff of legend.
Some of you may have already seen this, some of you have not. But it wasn't the FSS that led me to this particular planet. It was just plain old explorer's curiosity. And perhaps a secret, subconscious desire to spit my drink in my lap. I can't say with certainty. But I do know it's wasn't some bit of data on the FSS. It wasn't the planet's appearance on the System Map.
