I don't get it, I mean....

He comes across as quite generic?

The Nerd and the Critic had/have a memorable gimmick, instantly recognizable. The Nerd with his white dress shirt and glasses, and the Critic with his tie worn over his white tee, paired with a cap and sports jacket,

The choice of clothing conveys who they are and what they are upto, I mean. The Critic's tie is meant to imply how much of a pretentious pseudo-intellect his character's supposed to be, it's meant to make the audience laugh at him, I suppose. 

Joe otoh, his attire seems to be a generic leather jacket with a Superman logo graphic tee underneath?

He also seems like someone who doesn't have a sharp distinction when it comes to playing an on-screen persona vs. his actual personality, that infamous interview with Geoff Keighley back in 2010 or so and his personal video response to that, comes to mind, among other instances,

Apparently, when ThatGuywiththeGlasses wesbite was getting big, the management wished to diversify it by coming up with separate sites/channels for gaming and comics? Blistered Thumbs was meant to be anchored by Spoony and Joe together, it seems, for games (Inked Reality by Linkara, for comics)?

I can understand Spoony having been a big name back in those days, I haven't watched his content much, tbh, but it seem to be due in part to his charisma as well as a persona that's meant to be an everyday man (unlike how theatrical it is with AVGN and NC?)

If Spoony already was CA's "face" for gaming, how did Joe manage to carve a name for himself and eventually become more popular, then?

Is it because Spoony's interests were more on PC gaming, which always was a bit more "technical/niche", compared to console gaming, which is more casual/mass-appeal, and that's where Joe filled that niche?

If Spoony hadn't withdrawn himself, I feel Joe today would have been nowhere near as well-known as he might be right now, Spoony would have likely also had a way bigger audience and reach, likewise.

So....what was Angry Joe's appeal that made him big, arguably the one who has the best career, right now, out of all the Channel Awesome alumni?
