Just another Personal Page

Let me preface by saying that I had no idea what blogging was 3 months ago, but I think I’m ready for some critiques. My site is geared to my friends and family but I want it to look as nice as possible.
I’m running Exhibit, style switcher and the timeofday plugins. (I’m looking for a way to make the comments more friendly looking. No one in my family has any clue about most of the gibberish that appears with the comments. )
The site is located at https://www.jetshack.com .
I’d also like to know if anyone runs into a can’t modify header error. I was having problems with it when I inserted the style switcher plugin. I think I have it fixed but am not sure.
later
