Will anybody be willing to do a blog comment exchange?

Google loves new content and that includes comments. You can tell me what you want written on your blog comment and vise versa..

PM me your site info

i was thinking about a site that is like an exchange for article posters.. posters make a profile that tells what they know about so buyers can find people to post for them and have a decent idea if they know what they are talking about by their profile+reputation
