I think it might make more sense to allow visitors access to only last six days, but allow voting of members in the archives. Many pieces I've found in archives that were very useful and worth my vote, plankton or not. I'm very new to computers in general, but except for robots such as @cheetah I cannot see how even whales can have viewed every post that's put up daily or even within six days. I have trouble viewing just those fifty I follow as often as I would wish. The advice we newbies are given is to vote 10-15 times per day, but this is very difficult to do. Adding up the posts, which have to be found, read and worthy, and adding to them the replies and comments and replies to replies, and even 15 Votes is a great many. As our company expand exponentially, the points you raised of Views / votes becomes more widely problematical. If visitors were limited to just 48hrs of posts, and members could vote on up to a month's or all archives, then the value of the archival info would increase and the Want to join of outsiders would as well, without introducing such 'turn-offs' as pop-ups. There should be nil advertising. If you want to use your bandwidth to post ads for your likes and dislikes, that is entirely your $, but there is absolutely no need to decrease quality, just to increase quantity.
