Join a Respectable Forum
I have joined Digital Forum for weeks and it is a really informative forum where you can interact with users who are easy going and willing to help you in whatever ways they can, leaving good replies and comments on the forum is the key and this is the first forum that i have been to that has a system of how you can do your first reply and also your first post before you can add links to your signature and post.Digital Forum is a PR 7 forum and having a link within the forum is vital and good for your blog.

How to attract members to your blog
Since you have great articles created by yourself, advertise to the forum in a very discreet way or rather more like a blending post which allows your link to be placed for others to view.Gain trust from other users and you will see your traffic rise in your blog. Help others and write long paragraph of why you think that should be the answer and not just a "great!" or "way to go". This will not only be bad for your image as a postie but no one will be keen to check your blog contents out since you dont reply with reasoning, so its always good to give a longer comment.

Writing Articles in the forum will boost your traffic
Write an article in the forum and let readers view and comment on them, promote them easily and users who like your article will visit your blog and join your RSS Feed to await for the next update.Since always get first hand updated news, its always good to tell your users why RSS is easy and good to join so that they will understand.Make sure you are in a highly reputable forum so that you can have a good start to ensure traffic from forum to your blog.
