I read the article and comments below it. The recovery the article speaks of hinges on a reconsideration request to Google, yet they should only be sent if you are manually penalised (as many of the comments highlight in this article). That makes sense - Google are all about scalable operations. Creating an algorithmic penalty, and then waiting to manually handle and deal with a completely unknown number of reconsideration requests based on an algo update isn't scalable. If RRs are based only on manual penalties (and the consensus seems to be that is the case), then Google know exactly how many RRs they could expect and therefore deal with.
In any case, the article is a rehash of a lot of things we've been over here with many people simply not seeing recoveries: write great content to win links, reconsideration request (been over that one), disavow links, wait and wait.
In my opinion, better advice is to simply focus on new traffic streams while continuing to improve/optimise conversion rates. Waiting til Penguin 3.0 in October 2013 or April 2014 or whenever it will be is not really viable for most companies.
