I find it easier to promote blogs since I do not have to join most blogs to post my link in the comment section of a blog since a lot of blogs let anyone post links for your website after you comments as long as the comment is not spam, but with forums you have to post about 5-20 posts till you can access your signature or can post links on your topics and replys via your signiture or posts you wrote on your forum and reposted on other peoples forums by using a source link to link back to your forum on a topic on someone elses forum. Plus, a lot of forums are very strict on posting links to other forums.
Social networking sites are also very difficult to promote since if there is not an active community then no one will join since Social sites topics are too General like "General chat" forums which few people can make successful compared to a web design or graphics forum.
