http://sloblog.io/ - simple, responsive layout, Markdown everywhere, syntax highlighting, BrowserID/Persona-based signup, native comments + subscriptions, JSON export.

Coming soon: full API (someone's already building an iOS app on it), anonymous posting, authenticating against Twitter (not just Persona), Flattr integration.

No ads _ever_, monetization through Flattr, and I may eventually do a full open-source release. (My business is in training and consulting, not in running websites.)

Enjoy.
