If it was me I'd make more use of bold and italics, particularly in situations like the post where you listed all the countries.
the topic is good..but if you have a good logo for your blog and also a perfect themes for your blog..it's perfect..but for now..I think it's too ordinary man...change the font and what can I say that..rebuild...
My suggestion is to add from Feedburner "Subscribe by email" icon. Also will take affect adding of Technorati.com icon.
I'd say add one or two relevant images between your paragraphs... There's too much text and it gets boring to read.
