How to gain traffic for your current blog?

The fastest way to get incoming links: create a REALLY REALLY great site with LOADS of useful and informative content --- and links will come to you without you begging for them to link to your site.
Well, ok, that's the best and ideal way to get links but not necessarily the fastest. But many here are forgetting that sites you want links from - the quality sites in your field -- are also looking for quality sites that they can include in their list of resources or recommended sites. And you don't even have to reciprocate their link.
For fastest, search Google for "Add URL" or "Submit Your link" and submit your links.

I've found that writing articles about my topic and submitting them to article sites has worked really well. I think this is a good approach for small and relatively unknown sites... although you should be sure to submit to article sites that link to your site, not just reproduce the content and/or frame it!

Last but not least, TRY this Website Promotion or BigDirectory.org - free url submission, online website directory
