After seeing this alert about vulnerabilities in Flash, I'm finally getting rid of Flash on my MacBook Air.
Here's Adobe's instructions on how to uninstall Flash player from your Mac or you can follow John Gruber's method of removing Flash.
Google Chrome works as a stand-alone Flash player but most of the popular services (i.e. YouTube, Vimeo, etc.) offer HTML5 based players.
From my afternoon of usage without Flash installed, any site that pops up with a missing Flash player error so far has been because an ad wanted to play. So - not missing much. The only issue I'll have is needing to find a better player for the live feed at SSKTN.com.
