I think any action that takes you closer to G's guidelines is a positive move. Maybe the time is here for us all to be brutally honest with ourselves and conduct a sweep of our metas and content, anchor text and headings.
True enough, but let's use caution and not get caught up in "overSEO penalty paranoia" and start reversing what is still works and what is normal to Bing, Yahoo and the rest. Some have suggested deleting your meta keyword tag altogether. I won't do that. What I WILL do is use common sense to tweak it to not be spammy or irrelevant (something we have been doing since being clobbered by the MayDay 2010 update).
As many of us have painfully learned already, if you trust what Google says today, you're just setting yourself up to be burned tomorrow. Beware!
Happily, in the past week, I'm seeing many more relevant referrals coming from Bing! When you compare results for the term, Google's results are beyond laughable. Google should be truly embarrassed by the poor quality of their current results.
What they need now is an Orca update to eat that stupid Penguin.
