I think it's a shame too that it would be lost although I don't see how it could be filtered from the spammy repost n run mob. The thing am Amit showcase Sunday is that it is one day and posts (which aren't milking) should be clearly stated that they are reposts of older material with a bit of whizz band reworking.
It's a tough un!
I really enjoy searching and going over my old content and repairing it, as well as reading the many missed posts of others. I think sometimes, the context it brings from the past is invaluable.
I think it is hard to filter out the wheat from the chaff in this case.
