While limits users to 140 characters per tweet, Woofer requires each post to have a minimum of 1,400 characters.Similar to Twitter, Woofer counts down the amount of characters you have inputted with a big number at the top right of the screen. But you're not allowed to post anything until you hit 1,400.

Woofer calls itself an homage to Twitter, but to avoid any legal problems makes sure to include statements such as "We are not affiliated in any way whatsoever with Twitter."

Woofer's user interface is near identical to Twitter, however. The service also urges users to tweet about Woofer and for a while Woofer was "borrowing" profile pictures from Twitter users.

Last week, I tried to post a gigantic "woof," by taking the text of a short article about Shaquille O'Neal and using the copy and paste function to get up to about 1.6 million characters.

Here's where it gets a little weird. Woofer asks you to type in your Twitter username. So I typed in my real one (JBrodkin) and my 1.6 million character woof appeared, along with my real profile picture from Twitter.
