I would definitely favor this. There is a lot of "evergreen" content of tremendous value here that just becomes part of the decaying compost heap after 7 days, whereas, if there were opportunities for it to continue to be profitable, people would post quality things they could link to in future posts -- and continue to build value for themselves and enrich the community at the same time. This is definitely a way to increase the overall value of what's available on this platform. Good for you for bringing it up.
