Why don't Classified Ads have dates on them?

We’re sent commentary and requests on this subject on a regular basis. People’s opinions are split; many sellers & buyers want Classified Ads to be dated, and many don’t want dates. Although we do strive to make our members and visitors happy, sometimes it’s impossible to make everyone happy, especially when popular opinion is split in this way. So, after a lot of thought we decided when a Classified Ad was posted and the current length of time it is set for is not really all that important (due to the constant possibility of changes) as long as the information in the listing is accurate.
