Every reddit page while not logged in is full of hidden content from other unrelated pages. When you search, you'll get hits in these unrelated pages-- but when you follow the link it's not there (because it's on the unrelated pages).

Worse, the pages with the correct content aren't necessarily in the results at all because it was low enough in the thread that it was collapsed and wasn't visible to the search indexer.

It's not a total loss, but I'd say about 80% of my own comments are now difficult-to-impossible to find via search when they were easy previously.
