when you develop a site ....when first time your site come on pr1 than its good ...bt not for ever ...
PR is still important i guess since there are lots of possibilities that your site will recieve visitors. and a click that comes from google search has lots of impact.
PR1 is a start At least it shows your site is not banned and means that it's indexed (at least 1 page) every next PR level is times harder to achieve though
Of course pr1 is better than pr0 . This is true high pr is not important if you are gating more traffic in low pr. pr just show how important your site for google .
well PR is just considered in 200 signal to determine search ranking by G but it is not important as keywords and content stuff so just dont bother about how much pr u are getting just try to get more quality back-links then PR and search ranking increase effectively...bust luck
PR is such a distracting and misunderstood metric. It literally only gives an indicator about the strength of one page. For example, this site is large well linked to and well respected... yet this page has PR 0. Don't spend so much time worrying about PR.
