Definitely WordPress needs something for fast and easy publishing from mobile platforms! I would love to take a picture (or two or three) and publish it with two taps. Without thinking so much about formatting, about inserting code, galleries, or things like that. Mobiles and tablets are spreading everywhere, an any modern platform should be ready for this easiness of doing things. I love to take pictures of my animals or experiences here and there, but it's not easy to share them from the phone to my blog. I'm tempted to send them to Facebook instead, Google+, etc., and I don't want to: I want to keep them mine, on my own server's blog.
I think, looking to the future, that any platform should be really really aware of becoming mobile and tablet friendly. Today, for me, the WordPress iOS app is a shame, where you need to fight to understand and control. It should be easy, friendly, and FAST.
An example is the Tumblr app (https://itunes.apple.com/es/app/tumblr/id305343404?mt=8). I've used it in the past, and it's quite similar to what I mean.
I'm trying hard to keep using my WP blog, to control myself my information, but as I use more and more mobile apps to share, I feel more and more how painful is to post to WordPress from iOS. From the iPad I'm using Blogsy, but again, it's slow, difficult, and you need many many steps to just post a simple thing.
Anybody else agree with me?
