This should be your Bible.
The post on the front page is not how the majority of teams rotate at higher ranks, and it should not be how players at lower ranks learn to rotate. I believe it encourages ineffective behaviors, such as two players bunched up in the corner and nobody ready for a far post pass. I saw a couple of comments pointing this out, but they were inexplicably buried in the comments section. Here is a more effective basic guide to offensive positioning and rotation. Be prepared for some awful Paint editing.

These should be the default positions that your team sets up almost every time you have a "halfcourt offense" opportunity. I'll run through a few scenarios as well to see how these positions operate and rotate.
Scenario 1: successful pass to middle http://i.imgur.com/msVxeeh.png
1 attempts to score, 3 steals boost and replaces 2, 2 reads the shot/save to follow up on the ball
Scenario 2: clear to right side of pitch http://i.imgur.com/tBGZZVE.png
2 tries to block the clear and replaces 3 as the passer, 1 swings in behind 2 and is now trying to block clears, 3 tries to steal boost and shifts to the scoring position
Scenario 3: clear to left side of pitch http://i.imgur.com/lGYUICr.png
1 tries to block the clear and replaces 3 as the passer, 2 maintains the position as defense/blocking clears, 3 becomes the scorer but is wary of a failed attempt by 1 and ready to streak downfield to defense (note: this scenario does provide for more ambiguity, as sometimes it will be beneficial to have #2 attack the ball first rather than #1)
These are just a few of virtually infinite scenarios, but hopefully it gives you the right idea of effective 3s positioning and rotation.
Edit 1: added simplified positioning guides
Edit 2: Thanks for all of the feedback! I'm glad this could help some people. The graphics I made are definitely not well-designed and are indeed a bit confusing. If I find the time, I may revise all of this during the upcoming weekend. I will make the graphics much more simple and cleaner, and perhaps include something for 2s as well.
TL;DR: the post on the front page shows ineffective positioning.
