The layout does not look professional, I think it can be significantly improved. The site would look better if you had 2 columns instead of 3, you should make the column with your text significantly larger. You should change the color of your adsense ads to make it blend in with the theme of the site.
I think there's a lot of work needs to be done to redesign the layout. I'm using firefox and there's an empty large space in between. As a visitors, I'm not sure what's the purpose of the blog anyway....Travel guide? It looks more like MFA sites to me.
font is too small, plus you may need to edit the template, the shocking green color makes it difficult to read plus its not easy on the eyes, change the background color from light green to a darker one.
really small font! needs to be bigger as can hardly read it. Ads also not in line, come off page on left hand side. Big white space betwen 2nd and 3rd coloums (categories and your ads here) Like the apple image and the green theme although think the whole site needs more work - good luck!
