PR. PR It is useless metric used by google to mislead all so called "SEO expert" by making them to look in the wrong direction, while they (the seo experts) are paying less attention to the possibly important things. This is PR.
But, because it happen so that there is PR mania all over the net and people buy/sell websites/post/links with high PR for rediculous amounts of money and the big G thinks that people can by ads instead of high PR things, now they will probably stop updating the PR for the public. There is 3 options here
1. PR will be updated just one time per year on one time per two years. This will redure buy/sell of PR because nobody will be sure what he is actually buying.
2. PR will be never updated again for the public. Google will know what the actual PR is for every website but will not show the real value to the public. It will kill the business of a lot of people..
3. PR will be hidden forever.
Anyway this is not a real problem because the experienced web masters can check the link profile for a website using Majestic or similar tools and check manually what kind of websites are linking and if they are trustfull. TRUSTRANK this is the thing we should look for and guess what - It is not written anywhere.
