Next few steps for my blog

I've been following some threads here and on another forum as well and ran across a crashed challenge. So far, I have about 24 articles with some very helpful information on there. My niche is in IT and I've been and still am working in IT. I provide a lot of local IT services for my area and decided it'd be worth a try spreading some knowledge on the blog.

I went ahead and done some pretty good keyword research for each article I posted. Today, I've decided to stop writing and start analyzing more at what I'm doing. Majority of the keywords I've chosen are 3k+ local searches exact per month and low competition. Some of my content came from questions I seen asked on Yahoo Answers.

I have about 130 backlinks that I've manually inserted in some of my answers (it was necessary and relevant) for the questions on Yahoo Answers. I have an account with a lot of IT forums and some that relate. I changed my signatures and it updated majority of my posts on those sites (which is about 300-400 posts), but I can't find my signature from google if I google the forum and my signature (assuming only guests can see it).

I have a twitter account with about 130 followers and I have dlvr.it to tweet the title of each article as they become published. Besides when I tweet, I don't get much traffic. I used to get about 80 a day and I've probably made about $6 over the last month.

Can anyone suggest some good tips for finding ways to increase my traffic? I'm only monetizing with Adsense (big box for each article with text wrapped around) and I think it'd do pretty good with the right traffic.
