Free 512 to full members with an empty house, Ok not a great idea but a good way to use up all the extra land since people dumping off main land. Bad idea (don't know if anyone tried this, or if it was just said but not fact ) Supposedly no market place boxes allowed on the free lot.
Good idea sandboxes for premium members and reg members can't access. Should hopefully stop griefing in the boxes. Yet most Paid members already own land so they wont be using the sand boxes anyhow.
Giving free furniture, well I call that a dbl edge sword. It kills the furniture makers in sl , prevents people from exploring in turn that hurts other retailers and in my opinion stops people from learning and maby staying in sl.
But it will make LL money because of the membership fee and IF a person stays they will have used up all there prims so they will need to buy a larger lot so land gets sold and monthly fees go up.
Now if they were really creator content conscious they would offer a creator membership and give 200L$ worth of uploads a month and a creator only sandboxes.
