UPDATE: Old adverts still in place - I implore SE to change them. Upvote this question to implore also. Somebody will come to our rescue... eventually... I'm sure.
I appreciate and even enjoy the fact that popular questions are advertised between SE sites. The one qualm I have is the same old top-voted questions get continuous attention in the advert box and become boring fast. Likely they're continuously contributed to and bumped.
For example, the MMO question from GameDev has been consistently advertised to me on StackOverflow over the past many weeks maybe months. I tire of seeing it and other reoccurring questions especially considering there are many new and interesting questions since then.
I'm requesting the SE inter-advertising algorithms be revisited and modified to stop the same old "interesting" questions from being re-displayed continuously and indefinitely. Possibly a sliding window of time should be applied to capture newer questions that are more recently popular. Otherwise a static queue of question adverts might be cycled using more recent content.
If I want to see the all-time highest voted or popular questions I can easily do that by visiting the [Questions] nav button of any particular SE site.
I don't have to mention Fallout Vegas Ammo packs and Karma, or How to Make Bacon Powder because they're burned into our brains from months of impressions.
