The most SEO value comes from the blog being as a subdirectory of the main site (like example.com/blog). So when the blog gets links, the domain example.com gets the link, not a subdomain. A subdomain is treated as a different domain name.
Having said all that, you can play the game of hosting teh blog on a subdomain name and thus attempt to dominate the results pages with multiple listings you control, from your main domain name and the subdomain name. It's hard, but you might just get it to work.
