Guest blogging only works if the site your guesting on is ranked better than your own blog. Unfortunately your blog OllEngg has no PR, and isn't even the top 30 million on Alexa, and only has 1 site linking in. Which means a guest post wouldn't get seen by anyone but you and the guest blogger.
I don't mean this as criticism...but rather as advice to those interested in guest blogging.
I disagree with The TAZZone on this point. I think that is part of the equation, but another part is exposure to a new audience--if there's a blog with a low PR or Alexa ranking, but with a bunch of Facebook followers or 1000+ hits a day, I'll benefit by their readers discovering my blog, even if I don't benefit from a high quality backlink.
