As far as Austrian friendliness go, I've heard through friends, read in books and here on Flyertalk that they can be very bigoted towards foreigners - even towards whites (northern European) - especially in the rural areas (same can be said for the U.S., Canada and Japan, among other places, I suppose) though I haven't had the opportunity to meet too many Austrians in such areas. Just be aware of those around you and know when to leave if you feel unwelcome.
I am sorry
Terenz , I do not want to be impolite, but I have not read such nonsense for a long time.
Austria is well known for its welcome towards tourists. The most demanding customers are probably the Swiss, (not very friendly themselves, by the way) and they choose Austria as their favourite winter vacation place because of Austrian hospitality.
As far as language is concerned, Austria has excellent schools and they learn English at a quite early age. Many will not speak English fluently but will direct you to the right person if they cannot cope. At least they will try.
Go to Austria, you will be met everywhere politely and as you asked, Salzburg and Vienna receive thousands of English speaking tourists every year and I have never heard of a single tourist in difficulty because of lack of language.
Remember that Austria is not a third world country with no schools and education. As a matter of fact, they could teach many a thing or two.
By the way, you also will not have to worry being attacked or shot at as in the US.
