In many ways I agree with you. But it's not easy to determine if the other person is sharing. Browse host is not always reliable. I can browse someone, gives zero results. 15 mins later I re-browse & they have over 600 files shared. Or vice versa. It's happened many a time.

Some people choose not to share due to pressures from their ISP & possibly their local copyright laws. If they have been asked not to share *** by their isp or lose service, then they don't really have much choice.

Then you have the newbie users, who start off with nothing. But after downloading for some time slowly build up some files to share.

But yes, there are people who are I, me & myself only. Never interested in sharing. Don't care that it's a share network. Don't care about giving back. Don't care about anything except what they download.

Just as important as sharing is allowing yourself to become an Ultrapeer which helps other people connect to the network. People who are UP's often don't have as many people uploading as they might otherwise. Just my thoughts

All the same, I do wish there was better detection of those who do or don't share. Other p2p networks have such abilities.
