Oscer,
There are a lot of reliable and fast freehosts out there. Lightning, PimpServer, SmutServer, etc etc etc...
You shit all over Coolness.com because it's freehosting services have only been open for a couple months. I've personally looked into Ray's configuration and our chief programmer tuned His system kernels and tweaked the source code of his httpd server to get the maximum performance out of the hardware as possible.
With the load Coolness.com's servers are handling right now and not even breaking a sweat, I would feel confident posting my galleries there. I would not be afraid of a few huge listings and the huge spike in traffic it brings causing any problems. (like I might at other new hosts)
Bottom line... shitting on the new kid doesn't make you look that great either. I've never done it to another counter, nor will I ever. I let the value of the product or service speak for itself. So if your freehost is as great as everyone says, then it'll be fine.
