EVE General Discussion

So Ive been afk ice mining for past few weeks which gave me the opportunity to read lots of f information. Talk to lots of people which would have been more difficult if i was constantly clicking buttons actually playing the game. Im not surprised about the changes. Its time to move on so im looking for whats next

Trading is supposed to be lots of isk/hr.....or is it? Ive heard its more about the .01 trading war against bots
I could do missions to raise standing with the corps, lower taxes and jump clones

Here are the things Im in the dark about...

What are anomalies
Complexes
Grav cites
Whats exploration have to offer
Are there cool things that only probes will unlock for me?
Why are fw missions more isk/hr...do they damage my standing with factions?
Anything else out there in space I am missing?
