Are you going to copy everything Twitter does? I'm fairly certain nobody likes a character limit. If someone is making long posts and you don't like it, don't follow them.

Removing longer posts from the Zappl is just spiteful, sidechain your project if you want censorship to be a cornerstone of Zappl. I just can't believe an anti-intellectual stance of 'people don't read long' is the driving force to censorship on Zappl.
