Use PHP to build a Twitter-like system on your site

Is it just me or is there a total lack of input validation? mysql_real_escape_string isn't going to protect you from code injection...

I haven't read the article in full, but I wonder why the author hasn't used laconi.ca (the free open source software which is used by identi.ca). Why should you be creating a new microblogging solution when a perfectly good open platform exists?

I only hope part #2 addresses the scalability problems #1 has before the site becomes a hit... ;-)

First, it's interesting that they call this an <i>intermediate</i> level tutorial/article. I'd definitely put a microblog in the <i>begginer</i> category (The "build a blog in 15 mins" screen cast is one of the first things people watch when getting into Rails).<p>Second, in the time it took to write this article, one could have built the actual app to provide for download or as an open-source project.

This is really insufficiently complex and/or interesting to belong here, is it not?

How about just installing laconica?
