Need advice: third party blog creation

Hi,
Is there any tool allowing me to create blogs in mass, but on third party platforms (blogger, wordpress.com...). I have finished my main site on a niche i am working on, right now i am writing articles related to the niche (about 25) and i would like to mix the whole thing with some rss feeds and post in different blogs.
I have found blogslammer on the forum but i was wondering if you can advice me.
I was also thinking about using imacro for creating blogs but it takes a hell of time as you have to record your action.. and it is not always accurate.
Thanks for any advice

I did see somewhere in the affiliate marketing section I think, there was someone with a twitter bot. You might want to go find him. I think he can help you.
