I don't like the splash landing page - just take me to the site and there is nothing very special about the design of the site when I get there.
What is there to review exactly??? You have an annoying page filled with ads followed by a common blogger blog!!! enough said.
Tone down your ads if you don't like to get penalize by Google for this, or if you want to add more visitors and get more clicks from them. Keep in mind that information will drive people to your site, not ads. They (people) can also be invaluable source of excellent PR for you.
Certainly needs a bit of a enhancement - e.g. change the template, add a few graphics. I have visited may blogs with similar content, but with a more enhanced (eye appealing) layout...
that interstitial was just a link thats not part of the homepage. here is a direct link: http://marcuswalsh.blogspot.com And ill take off the Adsense for now,It was only 1 ad on each post I dont see how thats a lot ive seen way worse.
