document: Craigslist : virtual community maintains human touch If it works why change it ? This might have been the thought on the minds of dot com executives back when Internet businesses were booming , and most of the Web content was free . Web sites were overflowing with advertisements of every kind and size . Now that dot com principals know better , Web ads are no longer the only path to revenue generation .
