Sadly, you have not read enough before making your conclusions. Webby shines with blogs, check http://www.locomotivation.com to see an example.
You can create a blog with two commands in webby:
$ webby-gen blog "My Blog"
...
$ webby blog:post "Nice weather today"

[13:27:47] INFO: creating content/blog/2008/12/28/nice-weather-today.txt
And it obviously does support categories/tags/article statuses etc. since you can give any property to your page.
