Every community has a few trolls and some immature members, but this doesn't characterize the community as a whole [necessarily]. I think your comment is a big generalization.
If you look at the press that this has generated I would say that, even if they are a minority of Reddit's active users, they have been successful in strengthening an immature image for Reddit as a whole.
It's very unfair from you suggesting that anyone calling for her resignation is a troll.
Sacking your most prominent staff member that is essentially the only one that happily & directly helps moderators.. with nary an explanation? Even if this push is actually coming from senior management beneath her, she's obviously oblivious to how her company is being run. I doubt that, Ellen Pao is basically pushing to make Reddit in her own image, you can bet she believes she's going to be more than "interim" CEO.
Reddit deserves a better CEO. Or it deserves to fade into obscurity.
