There are two categories of site which can have a PR of 0 on the homepage, sites which have no inward links or brand new sites which have not yet been assigned a visible PR, and penalised websites which have had a PR in the past but had it reduced to 0 as a penalty.

I understood that your website can suffer if a penalised site or "bad neighbourhood" site links to it, so those sites with a PR of 0 may be of harm, however the other category of sites will be of no harm. People were certainly talking about the dangers of links from poisonous sites and bad neighbourhoods a couple of years ago. Whether or not this is still a problem I don't know.
