One of the more interesting web sites is \"How Stuff Works,\" the creation of Marshall Brain. The Cary company is less than a year old, but it is ranked in the top 500 web sites. Each month the site receives around 1.5 million visits. Brain and eight other writers prepare articles on how \"stuff\" like chocolate bars, TVs, and toilets work. The site also has an on-line store featuring items with the company logo.
