I hate to say it, because I used to hate this client with a passion, but I've pretty much switched to WinMX for downloading for now. I still share my files on Gnutella, though. WinMX just seems to be faster and have alot more files that you can't find anywhere else... even on FastTrack. That, plus the fact that there is only one developer.
The multiple developers standpoint of Gnutella is both it's biggest strength and it's biggest weakness. If only all the developers could really get together and start making their clients 100% compatible with each other I think things would start to change rather quickly.
