Right now pretty much the only way to get free skills is through quests. Even then you'll have to end up spending over 150 plat to unlock all your skills. And I can't even begin to imagine how those poor people with low level characters are going to expand their skill list with so little money. At the very least Anet should reduce the cost of the capture signet, that way it'll be affordable, but you still have to work to find and capture your skill.
