CheLivz and Thaguy pretty much summed it up in simple terms. I've got a semi-drunken response, to take this how you will.
The Calibuuuuur community desperately need more of theses. Who am I to say that? I'm basically the random guy that hovers between semi-competitive and semi-casual, and the only people I can point to as "personalities" in the community are Hagrid, aka that one fucker that's involved with the overall FGC's latest debacle over sexual harassment (Aris) and a jew that consistently dies to money signs and challenges Thaguy's claim about being The Guy (Floe). Hell, I don't even know if they are real "personalities" that play this game.
Who else we got? AlexJ, the eyebrows of Norcal? What does he know or says about the game other than pick Amy, AA/BB your way to victory while leaving a trail of depressed and bullied gamers that inevitably dropped the game back in SC4?
Hates? This academic just sits there with a thesaurus and rolls his face into the keyboard for the semblance of an interesting read about community issues.
We can easily establish more personalities for the community through streaming, commentary during tournaments/ranbats, article content, etc. Hates is doing a pretty decent job with his weekly articles and we got lots of skilled players streaming that Jaxel isn't allowing to advertise on 8WR through easier means.
-Day9-esque tutorials
We don't really have much media resources to point new players towards. We desperately need more things like replays, match analysis, theorycrafting, etc.
Real quick aside; have anyone ever seen one of these things? Day9 (Starcraft personality) consistently puts out streams of him just talking over the damn game. Match analysis between pro players, game play set-ups, theorycrafting for noobs *and* intermediate players *and* aspiring pro/tournament level players, etc.
He churns out these videos daily the last I checked about six months ago, and has a ridiculous fan base to help support whatever the hell he's doing. And when he's not doing shit like this, he's commentating at some next level major in fucking Sweden or for MLG or whatever.
I know several local guys that happen to have streaming capabilities at home. I ask that whenever they actually do stream or have casuals with friends, take a moment to explain your thought process while playing or have some minor analysis between matches.
