LinkWheel

Expanding 

Your “focus hub” could be ANY page you wish to promote. For example a page on your website, or another Web 2.0 property.
To expand, you could build a linkwheel like this around a page, and then build a new linkwheel around each of the properties that are in that linkwheel.
For example, in the above image, you would continue building another linkwheel having Weebly and Squidoo etc AS the Focus Hub. 
Make sense? 
You could take this idea and apply it to so many different things I'm not even going to bother with covering more scenarios. Use your imagination!

Taking Over the G

 Use of the Linkwheel strategy can bring some serious Google domination implications. For keywords with lower competition you could easily take over the front page of Google.

Further Promotion of the Wheel

Alright, so while what I've explained could bring some great results, this will take it to another level with minimum extra work.
