This blog exhibits one of the major problems I have with startup blogs that aren't hosted on the site of the product (and even some that are actually hosted there): the lack of navigation to your product has stopped me from visiting your site.
I click on the word Rapportive on top expecting to be taken to the site but no I am stuck on the blog, I even went so far as to look in the article for a link but found none.
These blogs can be great for getting your product out there but it really sucks when they make navigating to that product harder.
