The latest idea is to create an HTML equivalent to the "Problem Reports By Tag" email.
The second prototype lists all the tags, each as an index into its own page. As a bonus, if the tag corresponds to a manpage, the manpage synopsis is listed as well.
Finally, we have something that is starting to look readable.
This more or less corresponds to kern PRs, although other PRs are also tagged. (A prototype that would mine the existing database for 'bin' PRs is not yet ready, but the principle is the same.)
