Customize the SharePoint public urls view

Hi All,

I am having the requirement that needs to change the site urls view.

Example: http://www.site.com/Lists/Posts/Post.aspx?ID=32
 
instead of showing the blog URls like the above, can we have URL in the below format:
 
http://www.site.com/PostTitle or http://www.site.com/Lists/Posts/PostTitle

Can we change the urls like above ? is there any techniques ?

I am intrested to know about this, please share your experience.

Thanks & Regards
