Random inputs are a great source of creativity starters, and Twitter is a wonderful place to look for them. Go to http://www.search.twitter.com/, enter a phrase of interest to you, and watch what links, ideas, and thought fragments pop up. (BTW - you don't have to be on Twitter to do this.)

I have searches going all the time on "innovation" and "creativity" that yield scads of thought provoking material - as demonstrated by yesterday's post!
