This post is to add a poll to my previous post. I didn't know about the 30 minute timeout.
This is going to be a very biased poll (being in PHP), and you should rename the thread and content to suit the poll itself. The poll is nothing to do with the title.
Mixing languages (C, PHP) and DBs (MySQL, Oracle) and packages (Drupal, Joomala), and techniques (AJAX) and "non-code-based" is just plain silly.
Sorry but this is a terrible poll.
