Much of blogging (and creation in any form) is often exactly that: an existing idea remixed or reconsidered from someone else’s perspective.

After-all, the telephone wasn’t all that an original idea for a long while before the idea finally reached a salient and effective point.

My take has always been: just because you and I have heard the concept before does not mean everyone has. And if one person finds it helpful to read in this way, that’s a nice thing to have provided the world. :)
