I'm not known in the velocity scripts but I implement the Blog entries as a RSS feed.
Maybe that helps you in a other way.

 Well, I tried something using Xwiki Query Manager. Code below -
 {{velocity}}
 #set($resultDocuments = $services.query.xwql("from
 doc.object(Blog.BlogPostClass) as blog where blog.published = '1' and
 :category member of blog.category and blog.hidden = '0' and doc.web =
 'Blog'").execute())
 #foreach($resultDocument in $resultDocuments)
 $resultDocument
 #end
 {{/velocity}}
 I get this below error. What is programming right and how do I enable this
 right?
 Caused by: org.xwiki.query.QueryException: Full form statements requires
 programming right. Query statement = [select doc.fullName where from
 doc.object(Blog.BlogPostClass) as blog where blog.published = '1' and
 :category member of blog.category and blog.hidden = '0' and doc.web =
 'Blog'] at
org.xwiki.query.internal.SecureQueryExecutorManager.execute(SecureQueryExecutorManager.java:88)
