Hey noglider, the 'oil the chain' debate is an old and contentious one. I see from your signature that you also hit on another great controversy: tire inflation (in this case, how much to inflate your tires). You have these two listed as bike maintenance fundamentals. Just thought it was funny and wanted to point it out.
