If it were me, I'd read up everything I could find about the algo change and its effects on various types of sites, and then look at those sites, and (trying to keep objective) see if I could figure out what could cause Google to profile my site the same way. (And I might ask a friend or relative or colleague or expert to look too, depending on how much of a hit I was taking financially)
It's an algo, so it's not human, and there's a profile out there, made up of hundreds or a thousand little factors. And some number of factors is likely what trips the switch between business as usual, and death in the SERPS. And some could be huge and some could be tiny, and maybe you're just skirting on the edge, so if you could find a few little similarities that you could change, that would send you back.
That's what I'd probably do first anyway. I have not seen anything (as yet) that would lead me to believe that a reconsideration request would do any good for an algo change drop.
