The "You don't have to respect other people's opinions" might be controversial (aka good) for philosophy purposes but dunno, i guess it's there in all the other websites for a reason.
For a first day impression, i feel like this webpage will end up unused and forgotten unless some things change. For starters, the whole "comment on anything, and we mean ANYTHING" can only go two ways. One, this place becomes the new reddit/wikipedia, with tons of "good" info and remains "the next big thing" for a while. Two, most if not all but a few pages end up empty or vandalized, with harmful opinions, wrong facts or simply trolling rampages.
Then there's also the fact that the interface might feel interactive, but it really, really is not. The "category" tool feels too much like Wikipedia's, and the Front Page feels too much like Reddit's. Wikipedia has needed to take several actions to make sure their categories don't fall into stagnation, like WikiProjects, integration with several communities (art, science and philosophy-wise) and the whole "featured article" schema. Reddit is famous enough to make such a front page sustainable, but other, less famous reddit-like websites haven't had much success.
Also, following the previous point, most options and uses of the page are hidden in plain view, so to speak. The default font usage and color combination feel dull and old, the editing is confusing (though understandable, and let me be clear on something here, i'm speaking for others, not for myself, because i can see where you guys in charge are coming from. If the moderators or admins feel like i'm criticizing too much and not doing enough, well, feel free to give me some power) and the ranking's not really optimized. Most if not all pages feel crowded with words and not enough "shiny things" to attract people's attention, though i expect that to change in the future.
Ultimately, keep in mind that this is only a first day impression. I literally stumbled upon this website hours ago, and have been this comment since. Sorry if i'm too harsh, it's just that i know that you guys can just ignore my words if you want, so i'm trying to give some actual feedback, which is more than most people do.
Anyways, it's a great concept! The execution might be lackluster, but it's only one month old!* Best of lucks with this new endeavor.
