I just start a blog 1 week before and post 3 blogs. Is there any blog post site?

You means to promote your blog? Try blogrankings or topblogging or bloghub or blogernity. If there's another one, please let me know.. :) P.S : I'm newbie too for blogging, and I promote my blog there..

I have a blog with 5 posts on blogger.I think there is no blog site which accepts your new blog.Try to enhance your blog posts and try to write interesting content.Then only you can submit your blog to different high PR blog directories.Keep up the good work.

I don't have any idea of site where you can earn for blogging if your blog is still new since as I experience they have requirements on your blogs. Some requirements are that your blogs must have at least under 100,000 alexa rank or you have at least PR1. Just continue blogging quality content and you can have a pr1 blogs.

No blog post site that want new site. Take a look in my blog if you are free.
