Posterous iPhone App Will Make You Finally Get A Posterous

At least it did me. Touted by co-founder Sachin Agarwal as a one stop shop for all your sharing needs, the Posterous app (now available in the App store) is extremely intuitive to use, and you don’t even need a Posterous to use it to start uploading photos, video and text, which, if you’ve enabled the Posterous “Autopost” feature will also post to your Facebook, Twitter as well as 26 other social sites including Flickr, YouTube, WordPress, Vimeo and Tumblr.

While you might be experiencing iPhone share fatigue (Instagram, Twitter, Tumblrette, WordPress and many others allow you to upload content directly from your phone) Posterous has always modeled itself on providing its pretty fanatical userbase with ease of use, the original idea of the service being that you could send an email to post@posterous.com and get a blog back, to which you the could send any other subsequent posts to post@sitename.posterous.com.

The Posterous mobile app takes off on this basic “no need to log in” philosophy, but supports geolocational tags, category tags and various levels of editing and privacy. And despite being buggy at points (one of my test posts posted twice, which was confusing), it’s pretty impressive how much you can actually do from the app (for example I set up my whole Posterous account) as opposed to WordPress, which has the effect of making you feel immobilized when blogging on the go because it does not allow you to upload media other than photos and lacks social sharing functions.

Winning “Keep It Simple Stupid” product strategy aside, it’s really hard not to root for the YC-backed Posterous; Their recent skuffle with Twitpic solidified them as champions of user portability which is always a crowd pleaser. Their user traffic has also risen accordingly boasting a 40% increase since June.

Currently funded at $5.14 million, Posterous’ future plans for the iPhone app include building the ability to directly edit posts from the app, landscape post viewing, multiple photo selection and showing attachments as actual thumbnails.
