I'll try to clear up some confusion with the Sticky option...
By default, when you publish a post, WordPress will the post as the top post on your blog's front page. If you've set other posts to Sticky, those will take priority at the top and your newly publish post will appear below any Sticky posts. Many users had been using Sticky for every single new post, which is not the correct use of the option. You should want to use Sticky for one or two posts that you ALWAYS want to be at the top of the blog or until you edit them again and remove Sticky. Many blogs will never use the Sticky option.
If you need to go back and edit posts to remove the Sticky option to return your posting order back to normal, see http://support.wordpress.com/posts/7/ to find he option.
