If you’re a blogger, then we’re sure you’ve been in a situation where you can’t login to WordPress or Tumblr, or you need to get something to the world fast via Twitter or Facebook.

Instablogg lets you set up a blog post instantly and anonymously in seconds. Even if you’re not a blogger and don’t want to set up your own blog, Instablogg is perfect for quick publishing.

I can’t see the service adding anymore features, as its simplicity is what attracts you, but Instablogg is seeking requests for features here.

Writing a blog post, instantly

You’re shown a familiar WYSIWYG editor as soon as you visit the Instablogg site. You don’t have to sign up or connect any accounts. Simply give your blog post a title and start entering in whatever you like, including pictures, video embeds, and a your text.

Of course, Instablogg doesn’t have a video or hosting service, as this is a no frills and simplistic approach to instant publishing. You can make the post private, or public.

You’re given a unique URL to edit your post, but if you lose it, you’re out of luck because there of course is no sign-up process to claim your post.

Obviously, if you’re a serious blogger and want your own design, themes, and branding, then you should look for another service.

Sharing your post

Once you’ve written and published your post and want to share it with the world, Instablogg’s simple design includes a share to Twitter button, a Facebook Like button, and even a share button that includes services like Digg.

You can view my example post here.

The service has two other interesting features considering its simplicity, built-in commenting powered by Disqus, and a unique QR code for each post.

Services like Tumblr and Posterous are super simple blogging platforms, but again, not having to sign up is a plus. Another option for anonymous blogging is a service called FearlessBlogging, but isn’t as simple as Instablogg.

If you’re just getting started in the world of online publishing, or you need to get your words or a piece of news out to the world immediately, Instablogg is the best anonymous service I’ve seen.
