I saw the #Cloudflare EmDash release, and it looks cool, but it's not a #Wordpress killer...
Without a compelling case for migrating (I get the premise of plugin sandboxing is cool, but the fine print is that EmDash depends on Dynamic Workers to run secure sandboxed plugins, which are currently only available on paid accounts), going to a clone of WP on what seems to be just a way to try to drive paid CF accounts won't sweep a majority of WP sites any time soon.
