If your been online almost no one is around, and its rather depressing when you want a game, a big cause of this I think is how slow the game is to get going which leads to extremly long games.
I cant see any viable strats that DONT have you build extractors off the bat(If anyone has any please put them forward)
So the way I see it, home systems should have extractors prebuilt and if any worries over balance then just take the cash it would have cost from the start pool.
Another option I would like to see is colony frigates regenerate antimatter faster or have a larger pool so when they jump to a new system they dont wait around for years before you can colonise.
Send it 2 systems over from where you built it and it takes over a mintue before it can colonise.
