There is no "norm" for a blog as such - it is a good thing for variety that a lot of blogs look and feel different. I took a look at your blog and it looks really good so there is no need to change the design - nice clear lay-out, easy to navigate, etc . . Here is a clickable link for it:-
TEEN PUSSY BLOG
I do have a few suggestions to improve it though:-
1. Add in some hand-written posts yourself to all the sponsors content - it will help with SEO.
2. Make sure you add in the Google Sitemaps plug-in as this also helps with SEO (it basically tells Google every time your blog updates).
3. You may want to look at restricting the length of some of the blog summary posts on the main pages - the second post "Judith and Kay Chance Encounter" for example is REALLY long. While it certainly doesn't hurt from an SEO point of view to have plenty of words on the main pages, it does hurt from a "look, feel and useability" point of view. You can easily restrict the lengths of the initial summary by adding <!--more--> at the section of your text where you want the summary to end (the person then clicks the "more info" text to read the full post and the home page looks a bit neater).
Hope that helps
