Posterous vs. Tumblr

I REALLY like Posterous. But today I took a lot of time debating whether to make a new site ( http://LeaderShare.com ) at Tumblr or Posterous. In the end, I had to go with Tumblr. The reason? It has a simple “submit” button, and a simple “ask a question” button. That actually made the difference for me.

You see, I want people — other leaders — to contribute short lists of 5 or less items that will help us try or retry leadership stuff. It can be a simple list, or a list with descriptions. Posterous lets you “contribute” but you have to register and jump through hoops. And because of this, it is not ready for what I want at a site for sharing information. 

What do you use?

Oh, and if you have something to contribute? Just go to LeaderShare.com and drop something in, ok?
