Miiverse browser update allows you to post & follow from PC
Last month Nintendo launched the mobile Miiverse, which is a way to access Miiverse outside of the Wii U. At the time, the service was read-only, but it has now been updated so that users can make posts directly from their PC, as well as view your friends and who you’re following. Updating your profile and your Miiverse settings are also available.
For those who don’t happen to have a Miiverse account yet, you can view any post just by virtue of clicking the direct link to the post, sort of how you can view tweets without owning a Twitter account. There has also been a reduction on the amount of time that must pass between posts, down to three minutes from five. You can check out all the changes by hitting up Miiverse from your favorite browser.
