That article is seriously flawed IMO. Limewire highly recommended for Linux & Mac, yet it's available only for windows? iMesh connects only to the iMesh net, not FastTrack as well? Blubster no longer shares ogg vorbis files (unless they were referring to 1.2.3 of course)? Morpheus connects to Gnutella
AND FastTrack? They wish. WinMX easier to shut down than FastTrack? Please!
I'd say they're on a par.
