blog autocommenter

I'm looking for something that can automate blog posts. Instead of spending a half an hour creating a blog post on my wordpress or blogger, I'm wanting something quicker. Something that can add keyword links, tags, etc.. I found this thread, but it looks old and outdated.

Just did a sb blast on wp small blast about 500 blogs. so I went back and checked a blast I did last week very little are accepted mostly all accepted are auto accept comments. So now I have custom comments unique domains/urls(in fact I use a completely different domain each time I blast)...
