I don't even realize the steps I took to see this, so I can't reproduce it at the moment, but there was a point in which I visited the questions page but had no tag filter dropdown. The other filters were present; I clicked the "questions" button again, and the tag filter returned. Perhaps I'm missing something obvious, but that seemed a lot like a bug to me.

I can now offer the steps where the "filter" disappears:

1. If open a fresh browser and navigate to stackoverflow.com, the "New" questions opens up by default with no tag filter, showing "recommended" posts and ordered by "newest".
2. Clicking the "Questions" button stays on "New" questions, adds the filter tag (defaulting to "all"), and shows "all" posts - still ordered by "newest."
3. Changing the "filter" dropdown to "favorites" filters just as one would expect and appears to work just fine.

So this is all behavior within the "new" questions view - some with the tag filter, some without, and when it filters, it filters correctly, so I don't think it's a matter of "you can't filter this list yet."

Perhaps I'm alone in this, but I just wouldn't expect the "filter" (or "show" or "order") dropdowns to just disappear or reappear unless I changed to a list that didn't support that functionality at all.
