For those observing: There's an in-game internet of sorts, but the real-life Internet plays the same role in EVE as it does in Real Life: it lets players chat, trash-talk, coordinate activities, steal information (hacking and "social engineering"), maintain databases and wikis, write web apps to organize their businesses and optimize their ship fit-outs, and keep track of all the info in the game through APIs (yes, APIs).
For many serious players, EVE is a huuuuuuge time-sink. It's mind-numbing at the micro-level but engaging on the macro-level, and crazy fun/euphoric at the peaks. Some people put more effort into running and expanding their corporations than they do into their real-life jobs.
It's a second job and a second social circle. Essentially a second life. I'm not saying that's a good thing, not at all - it consumes many players' lives and well-being - but the results of all this human labor unleashed in an unfettered free market are fascinating to watch.
