i don't play eve (or any other MMO), but have been following it for a year. this is "stuff that matters" for 2 reasons
first is the server load. ccp swapped out the node that normally hosts the home world and used it for this battle, they slowed things down in a planned way (time dilation), and there was lag beyond that. so this battle was the limit of their technology. if ccp is able to handle battles like this, the battles will get bigger, so what comes next, from a server and software standpoint, should be interesting
but maybe the more interesting aspect is that outside of the game, the 2 coalitions have built up technology infrastructure for organizing and coordinating the players. prior to the battle there was a huge push to motivate players to log on similar to the promotional blitz for a new game or a movie. and during the battle much of the communication happens outside the game itself - multiple channels of mumble, jabber and the web
it's news when twitter enables the arab spring. and it's news (to me) when 4000 geeks get together using online tools and coordinate their actions to achieve some goal (however useless that goal might be)
as for the game itself, i played for a few hours and found it boring. it's nominally played in a huge 3d world, but the locations are largely limited to small regions around a 2d "grid". the number of ships and weapons is mind-boggling and complicated, and the actions all more or less amount to selecting an from a menu, eg you don't aim at a target, you select it from a list. so after a few hours i found myself wishing it had a command line interface and quit
