WordPress is obviously an advanced platform. It's taking me a while to figure it out. Definitely some serious stuff going on.
WordPress started out as a blogging platform. People wanted a "newslike" look with an "author" and a "date the article was written".
But a lot of people are using WordPress for a NON-newslike website. They simply want a site that is dynamic and has a built-in search box.
That being said, it's pretty annoying for a non-blogger to be forced into having every post require an author, a date, comments and categories to be visible.
So why not just set up a static "page"? Because then you don't get the built in tagging features. Also, if you want to promote a new page on the home-page loop, I don't think a static page goes into the "here's a new page" loop.
It would be SOOOOOOOO great if the WP designers could design a "Twenty Eleven" theme with the date and author stuff stripped out.
Not hidden using CSS visibility:hiddden. I'm talking about completely gutted. Never existed, never will.
There are a LOT of people who keep asking how to do this. It should be a standard option.
