For example, as soon as I heard about Penguin and the 'overall theme' (compete with over-optimization) I went and made a few changes to one of the sites I work on (it gained spots almost immediately),...
Can you mention what on-site changes you made?
I have been affected by Penguin and I believe that it is about more than backlinks, but I am not sure where the over-optimization might be.
Take keyword spamming , its entirely possible this has been redifined and could now include keyword stemming. Overuse of a keyword that would be grouped in a venn diagram (thanks Leosghost) could cause an increase in your spam score.
Does this mean that while before saying create a widget, creates a widget and creating a widget would help you to rank for create a widget, now mentioning these variations could be seen as keyword spamming and affect rankings for create a widget and maybe other keywords as well?
