lol if it's so easy, I implore you to create a Twitter competitor... and to make your challenge easier, instead of it being worth $20 billion, we'll lower the bar to, say, $150 million. It's already been done..every major web 2.0 success has many clones that all tried but failed to gain the necessary momentum and marketshare to become as successful as Twitter or Dropbox, for example. Even Evernote, despite all the attention and funding it has gotten, is stuck in the ruts. Yes, the coding part can be replicated, but getting the users and traction is the hardest part.
