Navigation in SDN Blogs

Maybe it's just me, but I don't quite get how are we supposed to navigate the SDN blog entries... For example, I found this blog post through search:

https://blogs.sap.com/?p=46366

It says "part 1" - great, now I would like to read other parts. But I don't see any navigation buttons that would point me to the previous/next entry in the same blog... This is a standard feature on any other respectable blog site. Sure, I can click on the author's name and then look through all of this posts, but why does it have to be that complicated?

Also (again, could be just me) when I click on 'Subscribe", it wants to download some file on my PC (I have MS IE 7) and my security software goes crazy. What's up with that? Why is it working differently than RSS feed on the forum posts?
