One of the products I was disappointed in the other day just posted a comment clearing up some things about where their blog is. Turns out their main blog wasn't linked up where it was easy to find. Now it is! If you're a Buyer and in need of some nifty Excel templates to do the heavy lifting for you then you should check them out http://www.buyeranalytics.com

Also if you're an ISV or future ISV you should take a look as well. I think this is a great niche product idea.
