No sudden recovery here. My traffic has gradually crept up to about 3/4 of what it was before Jan. 19, from an original drop to 1/2. But the increases have been gradual, with small ones that correlate to the Penguin/Panda updates, similar to what occurred last year whenever Panda was run. My other site that wasn't hit Jan. 19 has increased about the same, so I attribute the increase to Penguin/Panda, rather than any kind of recovery specific to the above-the-fold problem.
I removed all above-the-fold ads within a week or so after Jan. 19 and replaced them with one below-the-fold ad only.
