I think a lot more people would have more land if it wasn't for the big difference in price differences.
It would be a lot more useable if the following two measures were implemented:
1) Tiers were scrapped as they exist, and you pay a fixed amount per sq m in the existing brackets.
For example: 512 sq m tier is 0.97c/m2; 1024 sq m tier is 0.78c/m2; 2048 sq m tier is 0.73c/m2, 4096 sq m tier is 0.61c/m2.
Currently, owning 3000 sq m costs a player $25/month, using my method it would cost a player $18.30.... surely having that extra land used is worth getting the $3.80 extra a month for rather than not at all because someone doesn't want to spend $10 tiering up?
2) A proportional calculation of cost depending on the amount of time you own the land.
Currently I am on the 4096 tier, and am due billing next week. As I understand it, I will get stung for the 8192 tier this month even though I only own land for one week, if I bought extra land today. The person I am buying the land from will also get stung for the higher tier for the whole month so Linden Lab is effectively being paid twice (perhaps 3x if a land dealer buys for resale) for the same plot of land, and a rather unfair practice.
This could easily be calculated on a daily basis in the same time as traffic etc is calculated, accrued through the month and charged at the end. It's actually a lot more complicated to describe than it would be to code, and would benefit a lot of players - and possibly even benefit Linden Lab as people buy extra bits of land rather than not bothering because its not worth going up a tier for a 64 sq m odd corner that appears nearby.
