I have two 13+ children who have moved their blogs over to WordPress.com and I am getting ready to give them permission to have access to the WordPress.com domain so they can update their blogs when I'm not looking (we use a variety of internet filters at home).
Although WP.com is quite clean overall, it would really be nice if users could have a preference in their user accounts to not be able to view Mature Blogs. It's not that I don't trust them - I think all users would prefer not to accidentally stumble upon mature posts/blogs if they were so inclined. Obviously, since it would be merely a setting in the user account preferences, a user could simply change it back.
I see this "feature" as something similar to Bing and Google's image and web searches were you can specify in the preferences under "Safe Search" either "off", "moderate", or "strict".
Since this would rely upon WordPress's existing "Mature" flag, this seems to me to be a relatively easy feature to implement that (I believe) would only further WP.com's commitment to being the best blogging community on the web.
The blog I need help with is massminimalism.wordpress.com.
