Dallas Clayton who is the guy behind the self published 'Awesome Book' sensation is self published no longer. Check out this posting here. Now he's published by Harper Collins. Lesson: If you work your butt off and already get a huge following for your stuff on your own your chances of getting picked up by a big publisher are drastically higher!... buuttt....unless he's getting some fantastic royalty percentage on that deal, why Would he want to get published at this point? Probably so he can take a break from constantly touring and promoting his book and getting on with new projects. Cool.
Check out Dallas Claytons site. Poetry, illustration, books and a lot of documentation of his book reading tours. Preeety cool!
