It would improve search engine ranking and browsing if the title of journal posts could appear in the <title> tag. This would make it "much" more likely that someone would click on on the search result when they found it.
To see what I mean, look at this search for my posts:
All the titles are exactly the same! They all say "Journal of markjugg (792)". It would be more useful to say:
"Witty Title of Post — Markjugg's use.perl journal"
There's no need to include "792" in the page title.
This issue affects the current installs on slashcode.org and use.perl.org.
Related, when you are viewing a comment of a journal entry, the comment title should appear as the page title, not the journal entry title, which is what currently happens.
