I would like to add a pinned page “Tags”, which shows all the tags that are in the blog and that is dynamicly created. So when I add a new posting with a new tag, this tag automagicly shows up in the “Tags”-page.
I haven’t found a way to do so.
Is there a way to show all tags, or a tagcloud or something?
Somewhat related: @matt recently shared this reply in a discussion about an Archive page.
According the roadmap for write.as, it looks as if we can expect an archive page sometime in the fourth quarter of this year. 
I wonder if the Archive page will be similar to such pages on micro.blog, which include an index of posts as well as all tags used.
