Alexa.com ranks www.armorgames.com at 985 as of the date of this post. I find it interesting that on google all you have to do is type in "arm" and armor games goes to the top of the list of auto-fill-ins. I think that makes AG pretty popular. Google suggests to you at "armor games" before "armor". I didn't know the site was that popular.
Not really; any website just needs traffic, aka people coming to an fro. I say that, come 2011, we will have enough traffic to beat Newgrounds and rival addictinggames. When AG gets more fame, more developers will get their game submitted here, which generates more traffic for AG, the user interface and streaming will give more traffic, more people will want to join, which would give more yield, the people who don't join but want to play games by AG will search for those games, which will give AG more bounce.
Oh, man I can't wait until we pass Miniclip. Also, I think ArmorGames is much better than Addicting, I've been with ArmorGames since it was the layout before this one, everything was lateral and the site name was "games of gondor" instead of the two swords dueling it had a shining ring when games loaded, etc. AGFTW
