Why do we use gold instead of silver?

Today I found out that silver conducts electricity better than gold (wikipedia).

Since gold is also so much more expensive as silver, Why do we use gold in almost all our electronics instead of the apparently superior silver?

Gold doesn't tarnish, for one thing. For another, it is much more ductile than silver. That means it's easier to draw into wires. Gold can also be hammered out so thin as to be a single atom thick, without losing its conductive properties! That's one reason it's also used as a coating in the visor of astronaut helmets. 

Silver, on the other hand, is much more brittle, and does tarnish. Devices with silver wiring would require much more maintenance to ensure that tarnish didn't interfere with the conductivity.

I hope all that made sense!
