Simply you cannot do a better Twitter/Facebook/Google/E-type/Mustang/GTO/Coca-Cola/Pepsi... Your new creation may look like the old thing. As long as you have a new idea, your product will feel different if you succeed. The brands I just wrote are good examples of this view. I'm sure HN community know these examples very well...

Twitter was viewed, at the start, like a microblogging tool but Twitter was Twitter, not a microblogger. Our "New Twitter" is exactly like the Twitter with a few (hopefully) well placed features, even simpler and easier to use. Tusulog may look like Twitter, feel like Twitter or function like Twitter, Tusulog is not Twitter. I'm writing this post before we're done with this redesign-completely-thing because of the latest meme by Dalton Caldwell which is trying to offer a new paid Twitter.

If you try Tusulog and send your opinions here I'll be glad...
