I'm curious as to the point of building a Twitter clone (other than because you can). It seems that Twitter has really captured the market for 140 char messages.<p>What is the differentiator here?
Here is a podcast interview with the Laconica creator that cleared a lot of things up for me: <a href="http://www.twit.tv/floss37" rel="nofollow">http://www.twit.tv/floss37</a>
"Laconica is built on PHP/MySQL open source software."<p>Given all the hullabaloo about twiter scaling, rewrites, etc, I thought it would be clear by now that a database driven website is not a good architecture for twitter-like messaging system.
