Howdy would you mind stating which blog platform you’re using?

I’m going to start my own blog soon but I’m having a hard time selecting between BlogEngine/Wordpress/B2evolution and Drupal.

The reason I ask is because your design and style seems different then most blogs

and I’m looking for something completely unique.

P.S My apologies for being off-topic but I had to ask!
