I'm still writing content to pay most of the bills. Somebody asked me once, "What do you write?"
I said, "Well I write kind-of-good stuff for $.02/word and really good stuff for $.05/word."
The point being that gurus tend to pay the best so if you want some good shit, swipe from the gurus in your niche. Try especially to get their older, indexed content from the high-pr pages, so that you can ride those coattails.
Everybody on the internet has half the attention span of a gnat, so it's not like anybody is gonna notice. Plus, using content from already-indexed, high-pr pages will actually HELP your site in the search engines--regardless of what some may tell you.
There are more really good reasons to use content that's already been indexed and well-ranked, but I think you get the picture. These gurus are too money-hungry to slap you with a lawsuit when a cease and desist will work just fine. But it's not like they're ever gonna notice anyway.
Go make that money, bro. Yes you can!
