Only articles, blog posts, inner pages and very few primary domains. This index showing pages which have really high authority, like Google itself.
What do we learn?
Get a blog if you already haven’t got one. Blog regularly with unique content. Tag the articles.
A WebmasterWorld thread is going on about it here.
Looks like we have an answer to this problem at SE Roundtable.

Hope no suck SERP anymore and like matt cuts say this just short term issue.
Agree with Widarta, hope it’s not for long time
You’re absolutely right – tagging is key. I never used to tag my posts, and since I started, Astroengine.com was finally correctly indexed by Google.
Cheers!

This issue really screwed over a few of my sites during that weekend. They were getting very limited traffic, but everything is back to normal now and I am actually doing better now that before this started going on.
google SERP suck?
maybe yes maybe no. I don’t have an idea on it.
I always think tagging is good but it really never give me good results so far.. But I think it’s other factors instead..
I think what it is is that inner pages are more targeted to more specific searches because the index page usually targets high competition keywords
Google has been decent for me. Put some keywords in your topic titles and expect google to send a few visitors.
it surely does……
You have to give Google what it wants. Keyword rich titles and keyword-targeted content.
