G1 is Shareaza 'terminology'.
I also dislike the that, but I try to talk as much as possible about Gnutella and G2 (which I find better then Gnutella2, which I can treat as another name, like GravityTwo
)
But don't confuse the users
G1 isn't meant bad, it was just the 'first' Gnutella, and unfortunately, Mike has choose Gnutella2.... But don't make this a flamewar... There were enough before...
Anyway, try the latest Shareaza at:
Freebase
