  2. Hey there would you mind stating which blog platform you’re using?
    I’m planning to start my own blog soon but I’m having a
    hard time deciding between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your layout seems different then most blogs
    and I’m looking for something completely unique.
    P.S Sorry for getting off-topic but I had to ask!

    any widgets I could add to my blog that automatically tweet
    my newest twitter updates. I’ve been looking for a plug-in like this for
    quite some time and was hoping maybe you would have some experience with something like this.
    Please let me know if you run into anything. I truly
    enjoy reading your blog and I look forward to your new updates.
