Integration of social networks into native Wordpress comments

Question

I was looking for the “perfect” comment system for the wordpress blog I'm working on.

Firstly, there is Disqus / intensedebate / etc ...:

Pros: Easy to configure, somewhat customizable (to the limit), removes the load from your server, social.
Cons: Syncing with WordPress can sometimes be a problem, external errors can ruin your comment stream, there is no return for users without javascript, a lot of built-in code.

Then Wordpress's own comments:

Pros: Deeply integrated with the blog, very customizable, saves a huge amount of javascript that is built into your blog, it is easier to provide backup options
Cons: Not native, social, ???

For me, Wordpress comments look like the best option.
The only problem is social integration.

My questions:
What should I do with the data that I receive from users AFTER they are registered on a social network? (I already know how to create an login login and get the necessary information back ...)
I thought about just saving them; email address, name, image (which you get from a social network), like what is done when people comment without a social network ...
The problem is that I have no experience with the wordpress database, and I have no idea where to start. Usually the best option would be to use wordpress codex, but I could not find much there.

PS; Please no plugins!
There are amazing plugins there, but I love learning how to do things on my own.
If someone could just add some useful links to me or theoretically what needs to be done, I would be super grateful!

Answer 1

I was looking for the same “solution”, but could not find the correct answer (for example, 5 months ago). I recommend a range of Nextend, Facebook, Twitter, and Google+ plugins. Perhaps you can see the code inside these great plugins. Here's Nextend Facebook Connect http://wordpress.org/extend/plugins/nextend-facebook-connect/ For me, this is the “cleanest and most non-intrusive” way to implement social communication for comments in Wordpress, because you can process users as you like. and the comment template works the way you want to work. You can look here http://dfine.me/2012/11/500px-lanza-aplicacion-oficial-para-iphone/ to take a look at the implementation. An article that can help you a bit http://www.tutorialstag.com/create-custom-wordpress-registration-page.html , perhaps with this you can write "Social Information" in Wordpress db.
