Its definitely easily navigated but I think the design may be too simple. Try creating a more interesting header and logo. Good Luck
I agree with the above comments, it needs to be more visual, the top navigation is good and clear, scrolling pages and pages is not advisable though, need to keep it to 2/3 max (in my opinion).
The design using the white background looks too bland. I think it is also better to present a snapshot of the posts to grace your landing page instead of just placing the links to it. That would make it look presentable.
i suggest you to add some color there. so visitor can more enjoying your content. overall you layout is simple.
