Autoposts to your Twitter, Facebook and Facebook Page. You can invite additional authors to contribute to your blog at no extra charge.
The biggest request that isn't in Posthaven yet is HTML/CSS theming.
Posthaven has an open and up-front business model. You pay money, and we keep your websites online forever. There's no guess work about how the site will stay up, or whether your data is yours.
