A general software category might work. It should go without saying however that anything reviewed there should have a direct relation to Perl or a very common Perl task in some way or other. Editors is a good point; webserver daemons, database software for which Perl bindings exist or the likes might be other.

I'm not really partial to the idea of a column/article review category. Ovid's note was hardly a review (can you really review an article? what's next, reviewing the review? :-)), it was a meditation sparked by a particular set of arguments. I think you will find just about all other similar nodes are similar in spirit also.

I don't think there's that many categories that would make sense; a software review category sounds like definitely a good idea though.

Makeshifts last the longest.
