Two days ago, we started an experiment appending a Personal Tag to each post.
One thing we learned quickly, was that most of us didn't like the repetitiveness of posts displaying a tag, followed by a personal tag. For example, if rrrrr tagged a post with #privacy with a community tag of #linux, the tags were be presented as:
Based on suggestions from users including Aeiri and galen, we are trying a different format. In the feed display, the tag and the personal tag are combined. For example, rrrrr's post now will display:
#privacy · #privacy.rrrrr · #linux
Here, 'privacy' links to the #privacy tag page and 'rrrrr' links to the #privacy.rrrrr tag page.
#privacy.rrrrr · #linux
Similarly, '#privacy' will be blue if you follow the #privacy tag, and '#privacy.rrrrr' will be blue if you follow that tag.
As always, feedback is welcome.
