Over utilization of Wordpress?

Don't worry about it Dhaval. I have seen many blosgs using free platforms become huge. Have you paid for an upgrade? The .wordpress is not there in your site...

All that matters is content, and I can assure you that you have good content. Promote the site more (facebook, twitter, stumbleupon etc.) and create more backlinks (commenting, guest blogging). You should do just fine! Hope this helps.

Time is the best medicine my dear friend....Keep working on your blog...Hard work always pays off....It takes time to achieve what we dreamt off....keep working on the SEO (on page, off page, on site).....Best of luck.......

When it comes to ranking and traffic, Alexa is actually a bit unreliable especially when the traffic isn't a lot. Use Google Analytics & Webmaster tools to get an exact measure. :)

Dhaval, that's what I thought. But it doesn't matter if you are using free of self-hosted. Your site should have quality content. That's all. And your site has that. Give it time, I guess!
