This is one of those ideas that I think needs to discover some little nuance to work. Some use-case or utility it can slot into.
Context-less web publishing or is something that (IMO) has been tried in various forms and it doesn't seem to build momentum. The thing is, there are fairly easy no-specialized tools for this that a lot of people already use. Google docs & dropbox, for example.
The way I could see this taking off is for some sort of culture to arise around it. EG, it could work for 'ask/show HN.' Stuff that's needed for a limited time and for the purpose of a discussion.
Idea is good, execution is a bit shaky.
On my first attempt the post appeared and disappeared after I hit Enter in Author field.
URL definitely needs to be better. Do what word press does, if possible convert the title to url replacing spaces with hyphens.
Remember the Author name in the cookie. Next time I come prefill the author name.
Include author name in url like onetimepost.com/{author}/{title}. Great SEO.
While I have long thought there is scope for someone doing "blogging for those who don't want the commitment of a blog", I think your MVP is a bit too MVP.
One thing you could do to instantly improve is use better URLs for entries - even something like onetimepost.com/23982/ has to beat what's there now.

What's a 'tittle'?
Is this any different from what pastebins offer?
having issues. Returning empty post id. http://imgur.com/kRdV7gm
So how do I read other people's blogs?
I had a similar idea with Urgeous: http://urgeous.com/
It lets one blog by email, without the necessity of prior login ("no login necessary... or possible").
It's not generating much interest but the one consistent advice I got was that people would like to personalize the experience (register their own handle instead of having their posts listed under a number).
So I'm working on this feature now.
Good luck to you anyway!
