I would tend to avoid rampant use of square brackets in node titles. Such use complicates or even thwarts some ways of linking to such nodes.

And, despite the strong preference to refer to the language as "Perl 6" not "Perl6", the nature of search tags is such that the tag for easy searching for "nodes related to Perl 6" is "perl6" because most search methods know that searching for "perl 6" finds things that mention "perl" and "6" (or, increasingly, even things that mention "perl" or "6", much to my annoyance and frustration).

There are already many brackets in use ... anyway I think adding the tag to the title is just a weak workaround.

IMHO the real thing would be a better integration of the keyword nodelet.

That is, at least providing an input box while editing a post and making them searchable.

Showing the keywords alongside in RAT and Newest Nodes would be a plus.

Update

OTOH keywords are not inherited from the root node to replies...

We (all monks) really just need to think of the "title" field as "where you put the keywords" (or really, key phrases).

I reckon we are the only monastery ever to have a dungeon stuffed with 16,000 zombies.
