Conde Nast looks like a bunch of chumps right now. I doubt Mike Raldi will last longer than a year if he has to raise funds in this way.
The people over at reddit have made two thing clear: that Conde Nast won't increase their budget unless they increase their revenue. And that their current budget is not enough for them to run reddit the way they would like.
I'm certainly not defending Conde Nast, nor will I blindly defend reddit. And I certainly don't expect any company to run a site the size of reddit out of charity.
I will donate, as I've been a long time reddit user who enjoys the site (though somewhat less as time goes on).
