In a comment posted on this blog, Keith Teare stated that Edgeio (the listings aggregation site) listings automatically expire in 90 days. The graph below shows the number of listings declared on the home page - curiously it seems to be increasing with no clear dips. Are listings really being expired, or is the number an accumulative numbers of all listings that have appeared in Edgeio even though they may have expired? (To be honest, I do see one dip - can you spot it?)
If you were to factor in linear decay based on age expiration that line would be flat.

Or at the very most a gradual upward trendline...
