I'm not sure if anyone will find this interesting or not, but I thought I would share this bit of info anyway. My person site (blog) homepage is PR5. It has maybe 25 internal links and maybe 5 external links. One of those external links is to a URL that I have never set up, and never parked. It has never had a landing page whatsoever. No search engine shows it as having any back-links at all. Yet this domain has a PR or 4. This makes me believe that: a) a PR of 4 doesn't mean a whole lot and b) Getting a page to PR 4 obviously doesn't take much.
Are you saying your blog has no backlinks from other sites? That is where you will get your PR from! What is your blog url? I'll tell you exactly why you have a PR5 Brad
and regarding techblogger, see http://64.233.179.104/search?q=cache:http://www.techblogger.net/ Does this cache contradict "One of those external links is to a URL that I have never set up, and never parked. It has never had a landing page whatsoever." ?
I'll be damned. I had that set up all of maybe an hour or so before I took it down. How odd. And regarding the links to greg-j.com, I know the site itself has a few links from digg, but the frontpage doesn't.
You never know when the bots hit, sometimes at the wrong time, lol But the pages that have links from wherever, have links to the homepage, and internal links do pass PR That said, if you have a website with 2 pages and 100 links pointed to page1 and none to page 2, but page1 is linking to page2, that's enough to get some PR for that page . I hope that helps.
