I was on the Something Awful MMO forum looking at opening posts. Each game has such a post (or, often, several posts) that are full of information about the game in question. For example, I mentioned in a previous post that the EverQuest thread may contain the best summary of the game ever. A lot of the game threads start off similarly jam packed with details.
But not the EVE Online thread. It is less about the game and more about the reputation the Goons have in game and why you should come join in on the fun. This is probably natural enough, as the EVE Goons have their own enormous wiki about EVE Online, the scale and depth of which is amazing. One of the best benefits of being in my alliance is that we have full access to that wiki.
But in skimming through the EVE OP, I did find one nice item that helps explain EVE Online.
That chart shows the high level options you have in EVE Online. It even includes scamming.
Edit May 11, 2016: Since Evelopedia is dead, the web version of the chart is no longer very useful. But somebody has created a spiritual successor to the chart, which you can find here.
