Post through E-mail: Consider, I'm explaining a possible approach on a task to my sub-ordinate or justifying a reason behind an architectural decision to my manager. This stuff can be very generic. I can convert this into a blog with no extra effort by just adding post@posterous.com into the recipients' list.
Post From a Browser: This is really effective. A blog need not necessarily be an original thought; it can be based on an article or a picture that I would come across anytime anywhere. Just select the content from browser and click on the Posterous Bookmark, add your comments and done! This way the frequency of posts goes up naturally. The blogs need not be huge write-ups; but even few random lines.
Amazingly simple and direct User Experience. I never felt like searching for something; everything was placed at the right spot.
Two way information channel. Reading and searching for topics of your interest is equally easy. And not only that you can build your own knowledge hub by subscribing to authors of your interest.
Feature rich. This is an element of surprise for most of the users. When things are very simple, quick and effective, it is obvious to expect some lightness towards features. Rich text editing, HTML support, variety of themes to select from, Tagging, RSS, Auto-posting to social networks, Google Analytics, Privacy settings - everything you want in your blogging website, Posterous has it!
