LINQ - Order Randomly
I've seen a few guys asking on stack overflow and forums how to order randomly using LINQ.
Here's a simple solution using Guid:

OrderBy(x => System.Guid.NewGuid())

don't think that will be random.

Guids are unique, yes, but they have a structure to them. The first 60bits are a time stamp for starters.

also seems odd since there is a random number generator in .NET :)

OrderBy is O(n log n). It would be better to use an algorithm like Fisher-Yates which is O(n).
