QUESTION sitemap.xml

[Sveninho]

For my blog https://www.svenscheuermeier.ch I use the News Manager plugin for my posts. Everything works great but I have a question considering the sitemap.xml.

My post automatically have a <priority>0.5</priority>. I have no experience how Google treats the <priority> attribute but still im a little concerned. My "Homepage" and the "Blog overview" have 1.0 Priority but to be honest, I wish it would be the other way around so that my posts have 1.0 priority ... i already tried to change it manually (by downloading the sitemap from the server) but every time I post something new its back to default.

I'm thankful for any information about <priority> and tipps how to solve this problem.

Also, I'm using "autometad 1" to generate a Meta Description for my posts ... this is ok, but not really what I want since I'm blogging about SEO and Usability ...

Thanks for your comments and help.
