I was recently talking to some intelligent linux administrators, and I was talking to them about linux and which distro to use. I immediately started the conversation saying that I was going to install Debian first, but they laughed and recomended I started on red hat or knoppix. I was wondering if I should start out learning on knoppix, because i didn't think that was one of the well known distros since I dont know much about the many linux distros that exist.
