Fridrich (CFOP) Method
Written by the members of the speedsolving forum in this thread: http://www.speedsolving.com/forum/showthread.php?t=3688
Basic Description
The Fridrich Method is similar to the Layer-By-Layer (LBL) method, because some of the steps are the same. However, the full Fridrich method uses several more algorithms than the layer by layer method, and combines some steps from the LBL method into one step for the Fridrich Method. Of course, more algorithms are needed for this to be done, but this results in faster times.
The Steps
1. Cross First, make a cross and on any side of the cube 2. F2L (First Two Layers) Then, you fill in the slots where the corners of the cross are missing. You insert a corner and an edge piece simultaneously during each insertion. There are 41 basic cases for this step, but it can be learned intuitively. 3. OLL (Orient the Last Layer) Next, you make the entire top side of the cube a solid color. The top layer does not have to be correctly permuted. This requires 57 algorithms, but can be broken down into two steps (2 Look OLL), which requires 9 algorithms. 4. PLL (Permute the Last Layer) Finally, you finish the cube by permuting the top layer of the cube. There are 21 algorithms to learn, but this step can be done into two steps, (2 Look PLL), which includes 6 algorithms.
Pros This method is relatively easy to understand when compared to other methods. Therefore, it is the most tested and most popular method used. It has a reasonable number of algorithms to learn, and sub 15 second averages are definitely possible.
Cons Learning all of the algorithms takes some time, and it requires a lot of practice to solve the F2L consistently in 10 seconds or less. Also, it has a slightly higher move count when compared to block building methods.

Roux
Roux Method is a relatively new method and is becoming quickly popular.
Petrus
Petrus Method is one of the more popular methods for speedcubing. It relies on "blockbuilding" to do the F2L efficiently.
Heise
Heise Method is a intuitive method requiring little knowledge of algorithms developed by speedcuber Ryan Heise.
Advanced Methods
Advanced Methods Contains some methods that require extensive memorization of algorithms and understanding of them.
