Or you could even go step further and do a 3-cycle commutator of L shaped blocks using a double turn for the interchange(? not sure if this is the right word)?

I don't see it yet, but I will keep thinking on it. My thoughts right now are that an interchange move would need to be a wide layer turn and would thus affect centers too. I am thinking from the perspective of trying to cycle the 6 corners and 6 edges that comprise the border to the two 2x2x2s in the pattern.

does anyone have any memorizing tips!

The more work you do up front in creating/bettering a memory system, the easier it will be to memorize later on. Start with a simple system at first, then improve to better systems over time. Your memory gets better the more you use it, so start now.

What do you mean by 'System'?

spamming "or you could just use petrus" at every opportunity
I haven't really contributed much, but maybe Hoya5? I am the only person who uses it (that really does show how good a contribution it is ), but I still think it's a decent method.

Ahem, you are not the only person who uses hoya5. I'm not that good but I got a 2:21 single at ABHC.

Yeah I also use what I would call Hoya5 - same steps as 4x4 Hoya but adapted for 5x5 - but does Hoya5 refer to a particular kind of adaptation? And if so, is there a description published anywhere?

There are many memory systems you can learn, and each one specializes in helping you remember a certain type of material. For cubing you should learn to work with letters or even letter pairs. Read the wiki entry on blindfolded solving for a place to start and learn more. Follow the links in that article to learn even more.

How do you get your times to go below your posts?

Hoya5 is when you solve three cross pieces (L/B/R), then solve either the BL or BR edge, and then solve that F2L pair. You then solve the other pair in the same way, then continue as normal. If you use AvG edge pairing, lookahead for pairing the remaining edges is very easy. At least it is for me. I only half-read what AvG said and just experimented a bit, so I think what I do is slightly different.
(I do a U/D mirrored version of what AvG does, making the semi-pair in LFd and using u moves to pair stuff... there could be other differences I don't know of though)

Ha! I just realized that you can make the cube-in-a-cube pattern by doing two 3-cycle commutators of 2x1x1 blocks! I don't know why I never thought to do that before.

How I do it, one of my favorite algs (it's an F2L alg done four times):
(R' F' R U R U' R' F x y')4

Or you could even go step further and do a 3-cycle commutator of L shaped blocks using a double turn for the interchange(? not sure if this is the right word)?

Or an alg for the L-swap and "commutate" it with a cube rotation
[U2 R' F' L F2 L' F D' F2 D R U2, x y']

What would some of you guys consider to be your biggest contribution to the cubing community?

For me, my CxLL Guide would probably be my biggest contribution. Its small, but I think it did help the community.

I suppose making Sarah advanced Skewb tutorials is the only helpful thing I've ever done for this community.

[U2 R' F' L F2 L' F D' F2 D R U2, x y']

An L-swap that is a setup to a half turn, as Robert-Y suggested:
[U2 F' L (R D R'): F2]

Hmmm.

The Boomerang method,
the 2x2x2 optimal solver with the compressed look-up table, written in Matlab (thanks Stefan and Tom!),
and the Roux example thread.

Your Boomerang method is awesome

Perhaps I am just being dense here, but I still can't see how to cycle an L shaped block. Thank you all for posting your algs, but I am trying not to look at them until I can figure out the basic idea you are using. If I get stuck, of course I'll look at the algs. Once I understand the idea I definitely want to look at the algs you have here and see what they do.

Before I start studying the algs you all posted, when you say an L shaped block do you mean one made up of 2 corners and 2 edges? For example, one such L shaped block around my 2x2x2 cube-in-a-cube would be at UB+UBL+UL+UFL. Do I understand the L shapes correctly? Or do you mean an L shaped block like UB+UBL+UL? Now that I think about it, the latter seems to make more sense.

I'll post again if I figure it out.

 

[Robert-Y]

I meant a pair of edges and corners that form an L shape or even a J shape (Think about the L or J perm to help).

Popularizing some pyra methods, mainly 1-flip. Also making florianed pyras cool and lego skewb torpedoes

Yep. Two of them make a layer, three of them make the part of the cube that is affected by cube-in-a-cube (minus twisted corners).

Well, I come up with all sorts of ideas, but they only serve to occupy the readers time since no one uses them (myself included for most of them). I really think just answering a few questions here and there helps out though.

To StachuK: Don't be so modest. algdb.net is really nice.
