If there would be no sharer, nobody would want to use gnutella and the network wouldn't exist today.
Not sharing is not caring, sharing is caring.
Blocking uploads is like you stopping feeding your pets, they would live not so long thereafter.
A network exists because of content, no content = no network.
They say the best thing to do is to share experiences with others.
Did you know that when there is an upload on your client, that means there is a download on another client?
"I like the iPod scam, in fact it always come in my searches when there are not any other results because some do not share the files I want to download."
-et voilà
etc, etc, etc
Edit: as per Stief comment about doing circles...
