Is this an SERP concern?

A commenter asks:

on your page:

http://alexking.org/articles

How do you prevent, that when a user searches in google like, say “From King Design to Crowd Favorite” on the SERP he is displayed by google the posting and not your http://alexking.org/articles page?

Like I see it, you don’t have a noindex on the http://alexking.org/articles page!

I’d never thought about this being an issue. To me, this is the same as the home page, the date and category archive pages, and links to posts in your sidebar – just another link to a post.

Any SEO folks out there want to chime in with thoughts/advice?
