I love this sort of change. I've always been stumped at how long the website was building and seeing those old news float by during the build certainly wasn't making sense. I didn't look into how we could shorten the build by archiving the oder news though. But not I see it has been done before, so having this change is good and the 5 year period for old news seems reasonable to me. Thanks a bunch!
