Ok, here are my suggestions.
1. Change the font to Helvetia. It's much nicer, easier to read and has less distractions in it.
2. There needs to be more of a boundary between posts. If you look at the images below it is almost as if they are the same post/s.
3. Make the 'buttons' in the image below slightly bigger.
4. Something just looks wrong about this...
5. Add a nice background picture.
