That’s a pretty big claim. I don’t know if it’s true, but when someone has only been exposed to a few sites, it’s important to remember that your perspective is limited, as is mine. In any case, best is also highly dependent upon the person and how they learn, and to what depth they learn. But, we also accept anyone here who agrees to be respectful of everyone and is willing to share and learn. We don’t care if you think we’re the best or the worst
By the way, I’m going to edit your post to get the link right, for some reason it didn’t work for me. But I did find the site via google and can fix the link for you.
