How do you guys manage to gain PageRank?

Through the year that I have had my website up and running(Tiger Tutorials), I have seen no PageRank increase. Its stayed at a consistent PR0. I have read many posts on how PageRank can be boosted such as this one:

• Reformat all your URLs to be human readable and relevant. Prefer /pages/profile/soandso to ?id=2495722485.
• Add unique keyword and description meta tags to all your pages.
• Use Google's webmaster tools to see if you have any duplicate meta tags.
• Use Google Analytics to see where your users are coming from and what it's coming from.
• Use wordtracker.com to find good keywords to target. Be warned, "never give them your real email address, they will spam the mess out of you."
• Have a blog to create fresh content, which drives up PageRank.
• Host your blog on a subdomain (blog.example.com), as a subdomain's PageRank feeds back into the main site. 

 I have fulfilled all of these criteria and still no results are to be awarded. Do you guys have any suggestions? Please share your own experiences.
