They’re out there, and proliferating almost daily.  But doesn’t need dictate supply?  Joe Q. Public must have a need for dictionaries of internet terms, otherwise web sites such as onelook.com, webopedia.com, and netlingo.com wouldn’t exist.  A recent survey revealed that 70% - 90% of average web surfers don’t know what a podcast is, or what people are doing when they’re blogging.  Seems to me that if companies want to sell to the public, then they ought to expend a bit of effort to identify to that same public what the products are that are for sale.  Just a thought.
