I've been a Certified marketing and technical coach for SiteSell's Site Build It! product. This very popular self-help package teaches people how to build online niche businesses through keyword market research, well-planned Web content development, Search Engine Optimization, and online promotion including newsletters, RSS, e-courses, autoresponders, online sales and e-goods, affiliates, blogging, etc.
I'm an editor at Wikipedia, and have made hundreds of edits and contributions, ranging from Radio Advertising and the Eames Lounge Chair to Paul Newman's racing career and Talk Like a Pirate Day. It's fun, but requires attention to detail. Let's talk about it.
Suggestion: also search my portfolio for "editing."
