Dont they drive you mad, stark raving mad,
If I asked a camping expert for advice on the best tent pegs they would tell me about metal pegs, wood pegs, plastic pegs, screw in or hammer in, notched or drilled, where I could get em and how much I should expect to pay.
BUT
Ask a technogeek about say " what antenna I need for my radio" the replies will be on the merits on trying to cross an Aaardvark with a Zebra in an aquarium, they will post a schematic of a Borg Warner Automatic gearbox for a DAF truck, tell you its not the antennas fault its you to blame, and totally ingnore the original question !!!!!!
