I think the best thing to do when pronouncing "W" is to say it slowly and completely. This way, people will not ask you for web addresses anymore.
Good call!
"H, T, T, P, colon, slash, slash, double-u, double-u, double-u, dot, areyousickofmetalkingyet, dot, com"
While I'm ranting about W - why is that the symbol? If it's double-u - the why isnt is UU instead of VV? It's not double-v!
Whoever came up with the damned letter is a moron!
