DotNetNuke 4.5.3 is much better than 4.5.2
I have been checking our Google placement and it already looks very good. With the addition of article syndication, our Google page ranking should impove even more. The article module is a little buggy, if there is something that still needs work. This was a free module from someone that has been too busy to make fixes or updates. I am planning on fixing the module myself as soon as I get a chance.
