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 this. Please let me know if you run into anything. I truly enjoy reading your blog and I look forward to your new updates.

Hello there, I do think your blog could possibly be having internet browser compatibility problems. Whenever I look at your website in Safari, it looks fine however, when opening in Internet Explorer, it has some overlapping issues. I merely wanted to provide you with a quick heads up! Apart from that, fantastic blog!

Hmm it looks like your site ate my first comment (it was extremely long) so I guess I'll just sum it up what I had written and say, I'm thoroughly enjoying your blog. I as well am an aspiring blog writer but I'm still new to the whole thing. Do you have any helpful hints for inexperienced blog writers? I'd certainly appreciate it.
