I'm sorry, pardon my ignorance. Why does it amaze you that no one has bested ebay? I'm not in the least surprised, primarily because of the traction/inertia that ebay has now. A bit of an orthogonal take: Chuck-e-Cheese sucks, I mean really-really donkey balls sucks ass, bad food, boring entertainment, a viral haven, I feel dirty after being there, but parents still take their kids there in droves. Why? cultural inertia, because everyone else does it, we'll do it too. Stereotype, joe sixpack, soccer mom, sheep, lemmings, hive mentality, whatever you want to call it, its the same thing. That is tough to break these habits. I mean, look at McDonalds. I don't see any redeeming value eating there but tons of people do. Its like the saying, "eat shxx, a billion flies can't be wrong." OK, done with rant, mod me into oblivion for bashing our cultural icons.
Definitely getting tired of this martyrdom fantasy where people post an opinion followed by something along the lines of "Go ahead and mod me down for having the bravery and courage to speak out against the vile things of this world which you sheeple blindly accept!"
And, no, I'm not going to tack it to the end of my post because it's so annoying that it's immune to ironic mockery :(
Don't pardon your ignorance because there is none, we should recognize everyone else's. Forget Chuck-e-Cheese, think of DisneyLand/World. As a child, people would act like I was deprived and lacked a good upbringing because my parents could never take me there. I was happy my parents never wasted their money and instead spent it on more important things. Disney is a money trap that has successfully marketed their product to convince children and parents that their children will be lacking if they have not visited their park.
Ebay is where the buyers and sellers are at, so it's where the sellers and buyers go. What do you expect them to do, go to a website so hip and obscure that nobody knows about it?
google => powerset,mahalo msft => zoho (they're full of fail, but still)
