I see there are purty lil colored icons beside url's. Is that just me, or everyone seeing that as well?
They're called favicons. If you have photoshop or any other paint program, you can make your own for your own site as well. It's actually very easy to make and upload to your site. Just helps brand your company and website, I think.
I don't mind it actually. Adds a bit of color. It does seem to push things down 'off screen' a bit at times though.
Here's an update on this from Adsense http://adsense.blogspot.in/2013/07/introducing-favicons-to-our-text-ads.html I use http://www.favicon.cc/ to make them
You can change the favicon with your desired one... this way your blog would look more professional I would say.
I reckon the favicon is fetched from your server, so as long as you have correctly installed one, it would automatically show up in AdSense as well. Kinda like it does with YouTube if you add custom URL for your channel.
