As of the latest update to Miiverse, it's now possible to embed posts online. Just click the "Embed" link at the bottom of a post near the Facebook/Twitter/etc. icons, copy the embed code, and then paste it on your website of choice. This can only end well.
Other changes: the Activity Feed now shows what post you received a "Yeah!" on, and the feed will show less "Yeahs!" than before; "Yeah!" notifications can be disabled in User Page > User Menu > Miiverse Settings; and the user page layout on the web version of Miiverse has been updated such that you can select and display your favorite hand-drawn post.
Thanks for the good word, "Tom at Nintendo."
