I have a wordpress site that I haven't touch for months now. Only have 6 posts. Never do any promotion. I visited it today, am planning to develop it for my business, and I was surprised to see that it has PR6 according to google toolbar. Here's the site that I'm talking http://www.edmartech.net It surprised me because I also have another blog (hosted in blogger) that I update regularly, promote it whenever I can and it only has PR4. What do you guys think?
