Shoot!...I relaxed too much at a time and I forgot to put a entry this week!
Well Akane. I think both limewire and youtube are illegal. Both are quite the same. But I think if we see at the point of the people who make products there will be a difference.
Limewire is thought to be bad than youtube. The answer is quite simple. It's because limewire is a P2P download software. That means you could get the genuine data without giving any credit to the makers.
On Youtube you can't simply download . And because of the problems of encoding, the video uploaded tends to be deterioted so it is not quite as genuine as limewire. So the video turns into a sort of advertisement.
Well...that's my thoughts it isn't quite reliable but I think it would help you.
