It was likely to be the biggest annoyance for users of Posterous; not being able to save your work as a draft. No longer though, because Posterous finally added this option to its web editor:
“Posting isn’t always spontaneous and wireless connections can be wonky. Today, we’re releasing drafts so you can save your work for later and prevent lost posts.
[..]
After saving a draft and hitting the Cancel button – your browser’s back button will work just fine too – your draft will appear in your list of posts appended with a ‘- draft’ label.”
This is good, because it means you no longer have to use this rather tiresome workaround any longer. 🙂
