    Hi there! Quick question that’s totally off topic. Do you know how to make your site mobile friendly? My blog looks weird when browsing from my apple iphone. I’m trying to find a theme or plugin that might be able to fix this issue. If you have any suggestions, please share. Thank you!

    I believe everything said was actually very logical. However, what about this? what if you added a little content? I am not saying your information isn’t good., but what if you added a headline that makes people want more? I mean %BLOG_TITLE% is kinda vanilla. You might look at Yahoo’s home page and see how they create article titles to grab viewers to open the links. You might add a related video or a pic or two to get people interested about everything’ve written. In my opinion, it might make your posts a little bit more interesting.

    I think everything composed made a great deal of sense. However, think on this, what if you were to write a killer post title? I mean, I don’t wish to tell you how to run your website, however what if you added a headline that grabbed folk’s attention? I mean %BLOG_TITLE% is kinda boring. You ought to look at Yahoo’s home page and note how they write article headlines to get viewers to click. You might try adding a video or a picture or two to grab people interested about everything’ve got to say. In my opinion, it might make your website a little livelier.
