Google Modifies Navigational Search Results

I reported this morning that Google has changed the way they handle navigational like searches. For example, if you do a search on a site's name (i.e. navigational) you now get a different type of result set then you did a week or so ago.

For example, a search on the popular will now show:

Show Google's cache of
Find web pages that are similar to
Find web pages that link to
Find web pages from the site
Find web pages that contain the term ""

Instead it will show you results that match the keyword phrase "" That includes links to possible competitors. I wonder if that will upset

In any event, I have compared how Google, Yahoo, MSN and handle these types of navigational queries at the Search Engine Roundtable.
