I enjoy using Posterous to blog. It's clean, simple and very easy to use. But there's one thing that's irked me from day 1: their "New Post" button.

There are two ways to create blog posts: via email and via web interface. I would think that pressing this button would navigate users to the web interface. It doesn't. Instead, it tries to open up an email client and send an email.

Posterous built itself up around email blogging, so I realize only a minority of other users probably prefer using the web interface. But still, if you're already on a Posterous blog, having that button send an email just seems counter-intuitive
