On PHPKitchen.com, there's a new post with some of John Lim's opinions on PDO and the state of the project - and asks the question "are we continuing to make the same mistakes?"

Lukas blogs about the recent Cancun PDO meet, [and] in general, I would agree with Lukas' conclusions.

PDO is not really a step forward. It's a lateral movement that attempts to show that PHP has a standard database API. Somehow I've heard this story before - PEAR DB was once meant to be the standard database API. That didn't work out either (not powerful enough, the base PEAR class was simply awful, never fully backed by the community, etc). Are we continuing to make the same mistakes?

He also poses the question of why the PDO design wasn't closer to the already established PEAR DB structure...
