I was hub-hopping one night and read an article about applying the Japanese principle of Kaizen to many areas of personal life. I thought, "I should write a hub about using this idea to increase Hub earnings." So I mentioned that to the hubber, and then I wrote my hub and added an anchored link to his hub.
Ain't nothing wrong with that, but as noted already...be careful about quoting other hubbers' work without permission or putting other hubbers down. That's not cool.
To quote or use someone else's work without crediting them would be plagiarism...illegal. And to talk trash about someone without warrant is libel...also illegal. But to simply mention another hubber and link to their work..."nicely"...all good.
If anyone wants to try it out, feel free to mention me and link nicely to my hubs anytime haha! Aloha, y'all...
