Is this just me?
Matt Cutts tweets about a Penguin data refresh but in his tweet there is a link to "Details" which reference Panda on webmaster central.
I don't believe there's any hidden meaning there, but it certainly clouds the issue for me.
Smoke and mirrors tend to do that. Imo just focus on your link graph, produce high quality linkable content and stay the course. Things like Matt Cutts using twitter instead of G+ are just.... distractions.
