What’s the minimum viable blog feature set these days?

• Rich text posts (output; the source can be anything)
• Titles
• Permalinks
• Tags/categories
• Navigation
• RSS feed
• Images hosted locally
• Media embed (remote or local?)
• Author info for multi-author blogs

I won’t back down on RSS/Atom, because there’s SO MUCH you and subscribers can do with it.

I also think images should to be built-in and not something you bolt on clumsily afterward.

Not sure if I’d consider comments part of the base level.

What else am I missing?

Candidate Software

Looking for something lighter weight than WordPress.

The last time I tried Plume and WriteFreely, they didn’t support images, though IIRC you could embed remote images in at least one.

Static site generators I’ve tried like Jekyll require you to bolt on separate commenting systems like Disqus, or jump through hoops to roll your own in a way that will re-generate the site when someone comments…and you still have to reinvent spam filtering.
