Regular NewTeeVee contributor Janko Roettgers writes this week about mashups for GigaOM. Reading over continued promises of a Last.fm’s music video recommender, Janko notes more than one user-created alternative already exists.

Take LastTube for example. It’s a great web-based video player combining Last.fm and YouTube, glued together with Yahoo Pipes and Adobe Flex 2. It’s been whipped up by one lone programmer in Colombia of all places, who, by his own account, only needed one day to complete this project, including “coding, testing, googling and lunch time.”

Janko suggests that if outside programmers can build a reasonable replication of what you’re doing internally, you may not have much reason to call yourself a business.
