I'm working for a client and ProcessWire might be a good choice. But part of the website is gonna be a tumblr-style blog.
1. In WordPress I would do Blog with post formats, each post format would get a own theme. Can I do something similiar with ProcessWire?
2. If i had a blog running with ProcessWire, how well is the tree-architecture? If I had hundreds of blog-posts with different categories, they all within PWs tree? No opportunity to sort by category/date/tag/title? So it's gonna be a mess to look at old entries, right?
