You must be very different than I am. I used to have Wordpress hosted blog which I would not update as much as I would like to. Reason? Whenever I was in the Wordpress 'New Post' window, I would worry about post formatting, title of the post, my potential readers etc. than about writing what's in my head at the moment.
With Posterous, if there is any idea/thought in my head, I simply write down an email and send it to post@posterous.com. If I have images to post, instead of uploading them one by one, I simply forward them to Posterous and hey, I get a nice image gallery on my blog. Even better, with Posterous' iPhone app, I could send any interesting picture straight from my camera to my blog. What I realized that I had created lot of artificial barrier to updating my blog and Posterous took it all away. I use Posterous exclusively through email (unless I need to delete/fix post) and I think it rocks!
Depends on what you're writing about. For a while, I never used the email posts, because it wasn't adequate to handle my code blogging. That's changed since Chris implemented markdown.
If you just write text and post pictures, email is great.
One of the strengths of Posterous is that it offers a good solution to both approaches. If you like the ease-of-publishing via email, it can do it. Web? Got that too. How about via an iPhone or Android? Check.
In Clayton Christensen's book The Innovator's Dilemma, he discusses two types of disruptive innovations:
1) Low-end disruptions
These serve less demanding customers with low-priced, relatively straightforward offerings using low-cost business models. Look for markets with over-served customers and offer a simpler product or service.
2) New-market disruptions
These serve new customers by making it easier for them to do something that previously required being or hiring specialists. Look for unfulfilled needs and create new products or services for them.
Posterous is a great example of a low-end disruption. They're offering a product so damn simple that few realized it would have such an impact (like Dustin Curtis). And now they've got features that early adopters and perhaps some early majority want as well (the rich-text editor). Pretty shrewd of them.
