  12. Hey I know this is off topic but I was wondering if
    you knew of 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

    I truly enjoy reading your blog and I look forward to your
    new updates.
