A search on google at Yahoo! Search confirms this to be true. In the past the results looked like:
Notice the category link, which links the search result directly to the category it belongs to within the Yahoo! Directory. Now that seems to be gone for all searches I tested.
Same with a search on search engine roundtable:
Old Result:
New Result:
I tried several different searches that I knew returned the category link within the listings, and all are gone. I do not know if this is on purpose, or if this is just a Yahoo! test.
