I don't think that there's a particularly good reason to hook the PHPAR validation into the CI validation class. I'm going to tackle validation in an upcoming video.
I realize that the Facebook comments are a turnoff, we're switching to a new solution shortly. It was an experiment that ended up to be not worth it.
Regarding SwiftMailer. I'm not huge on CI's email class. It's absolutely fine and can do quite a few things however I SwiftMailer is an established open-source project that is being actively developed upon. SwiftMailer supports ssl encryption and has extensive documentation. It supports multi-part messages and has a number of plugins such as throttler, logger, decorator, and antiflood. You can easily customize the transport as well.
Not only that. I'm not ONLY working with CodeIgniter. I also other PHP projects including one that is written in Kohana. By using SwiftMailer and easily being able to add it to my code I'm able to reuse functionality from one site to another despite the fact that it's written with a different framework.
Anyway, to each their own on the SwiftMailer library. As far as I see it, it just comes down to what you like to use.
