My idea is that parcel ownership should have a strict lower limit of something like 256sqm land per sim. This means that to buy a parcel of land as small as 16sqm then you would have to allready own at least 256sqm inside that sim. This is to limit the spread of adverts that are ruining peoples lands when they appear nearby. People who invest in land for places to live are spending a lot of money and seeing their land values dive when adverts appear around their homes so this will make land a much safer investment. This wont stop advertisements but would see them having to invest more in individual sims where they would have more prims available to use and would be able to create much more effective advertising platforms. I can also imagine that advertisers would approach land owners to be able to rent some advertising space which I am sure will benefit both sides. To do this would be simple.. You would need to add another check on parcel purchase that the person will be owning more than the lower limit of land. There also needs to be a check that either all the owners land is being sold in 1 parcel or they would need to have the lower limit (256sqm) not for sale. This would prevent people buying 512sqm cutting 16sqm for personal use than placing 496sqm for sale. The future of the internet is Web 2.0 and I know SL is something like it will be in future. Advertising is a big issue on the internet.. its everywhere but imagine websites where other people could just buy a space on your webpage and advertise while people are browsing your website. This is like what is happening on SL. The revenue generated from advertising should be going to those who own the website/region/parcels and create the content there.
