    Greetings! Quick question that's entirely off topic.
    Do you know how to make your site mobile friendly?
    My website looks weird when browsing from my iphone4.

    I'm trying to find a theme or plugin that might be able to fix this problem.

    If you have any suggestions, please share. With thanks!

    great points altogether, you just won a new reader. What
    would you suggest about your submit that you simply made a few days
    in the past? Any sure?

    I'm not sure why but this website is loading extremely slow for me.
    Is anyone else having this problem or is it a problem on my end?

    I'll check back later and see if the problem still exists.

    Hi there, i read your blog occasionally and i own a similar one
    and i was just curious if you get a lot of spam feedback?

    If so how do you stop it, any plugin or anything you can recommend?
    I get so much lately it's driving me insane so any help is very much appreciated.

    I was curious if you ever thought of changing the layout of your blog?
    Its very well written; I love what youve got to say.
    But maybe you could a little more in the way of content so people could connect with it better.

    Youve got an awful lot of text for only having one or 2 images.
    Maybe you could space it out better?
