Which of these are good and which are ugly?

They are on http://www.mashable.com

All ugly except the last advetise with mashable one

I like the BlogRovR ad.  Not much clutter. The others are all ugly.

My favorite are ones that tie into the site - like the one that said 'blah blah - it's easier than getting michael arrington to link to you'

We have a great one in mind for our app - I should mock it up and share

yes, you really should
