[sdiy] vero board and a couple other questions

[Steve Begin]

Is there any disadvantage to using vero board aside from aesthetics?  It seems like it would be so much simpler than a PCB but I'm wondering if there is something I don't know.

Also, is there any good advice anybody could give me on how to avoid capacitive coupling?  I understand that putting things too close together can be a cause of this, but how close is too close, does it depend on voltage and/or current too?  

Another question that I've been meaning to ask is:  What is so bad about flux anyways?  Before this board I'd never heard of 331 or 245, and to be honest I never even heard of removing flux.  

Yet another question, this one might be a little too big, so if it is, don't feel obliged to answer it.
Why is it so important to isolate grounds?  I keep reading on this board about good and bad grounding practices (as well as clean and dirty ground) and I thought ground was just a point of 0v.
