It really depends on what is convenient for your own use. I don't think
there is any particular style that should be preferred to another. Postfix
and Prefix are probably the most common and I think that Infix is more
rarely used, just because it is somewhat clumsy. Also, don't forget Map
(/@), Apply (@@) and  Apply at level 1 (@@@).

I'm fairly new to Mathematica and have a style question rather than a 
functionality question.

I'm aware with the operator forms for Postfix (//), Prefix (@), and 
Infix (~), and I've found the // operator useful for piping long results 
through the ...Form functions, or N, or the like, as a quick 
afterthought while typing a lot of stuff.

What are the analogous situations where @ or ~ are used?  Looking at 
random notebooks around I've from time to time seen them used but there 
doesn't seem to be any rhyme or reason; it's not clear when 
stylistically they'd be useful, as opposed to the // operator, which I 
can see and use myself.
