If you go to http://www.google.com/finance?q=vxrc on the right click on blogs right next to feed and news. It shows a post from a message board stockhideout. How do I get my message board to show my posts in there?
I'd imagine those where from Google's Blog Search... how will index is your blog? Do Google visit your site often? I would think a simple SEO, (use the keyword in the title of your post) and indexed by google it'll show up. Maybe you can try to link->out to google too...
