Hi!
You can use the serendipity_event_categorytemplates plugin to assign distinct templates to each category. There of course you can use your custom smarty template which has no title, date and meta stuff.
In a year of this now I have realized that MOST people do not just dislike blogs THEY DESPISE BLOGS!

You could have what looks like a website with all the auto features of a blog.
I completely disagree on this. People love blogs for their interaction, their chronological posting order, the way to discover more features in a blog page, the way to reference other articles, stay connected to a community. This is what has made blogs popular.
CMS systems with "just an article" have existed for ages and are getting less popular, look at how many new sites are being created that look like blogs (with sidebars, meta info etc.) or blog-portals. Most CMSes are even replaced with WordPress, Serendipity and the likes.
Of course there still is a need for CMS for complete info-heavy pages, but also there "just an article" doesn't work for most people. They need site interaction, user interaction.
Best regards,
Garvin
