I guess I'm a little late with the introduction, since I joined last September, but better late than never. I'm Dimitri. I stopped lurking and attempted to join right after I first tried to rate an article. I figured that before I could even begin to consider thinking about maybe possibly creating anything SCP related, I'm gonna have to read and rate every single SCP article. Then, I'm going to read and post a comment in the Discussion section of every article, since I will, then, probably know what I'm talking about when I give feedback. This is probably going to take a while, I only just read and rated SCP-183.
Yeah, don't do that. While voting on articles is all well and good, no one wants to see someone comment on all two thousand some articles.

A fresh newbie rating and commenting systematically on every single article is… probably going to get a slap on the wrist. Or worse.
Rather than forcing your judgment on the existing site material, how about getting on IRC with us and, well, getting to know us? And letting us get to know you? Discussing articles and what makes them great is a far more useful exercise than just going around voting on pages that have been around for nigh on five years.
Wel, right now I'm only rating every single aricle, not commenting. Although, I think I did comment on one article back when I was clicking "random article" over and over, but that one comment wasn't even criticism, merely an observation.
As for the IRC chat. Sure, I'll check it out.
Still think I should read every article, though…
There's no problem with reading everything. That's a great thing to do. There's also no problem with leaving comments every now and then. The problem is when you go through and comment on them all, which gets annoying very quickly.
Make sure to create a sandbox page for whatever writing you might do, and get drafts looked at by the forums and the chat before posting to the mainsite.
Then, I'm going to read and post a comment in the Discussion section of every article
Just a heads up, make sure you don't comment at too rapid-fire of a pace. It's great that you want to add your thoughts to every article, but the the best comment for discussion is one that introduces an interesting or new topic, and if you post comments too fast for people to reply to or consider, it sort of defeats the purpose. That said, it's great that you'll be reading all the SCPs (which is by no means required, but nevertheless commendable).
Welcome to the site!
Edit: Also, everything Mackenzie said. Hopping into chat is a good idea.
