Danny Sullivan started a thread named Who Cares If Google's A Portal. In that thread he posts five consecutive times, so demonstrate the conversation he had with a reader. The posts include a dialog between himself and a reader, who is upset with Danny's tone on his podcast, The Daily SearchCast. Specifically, how Danny was being a tad sarcastic about Google's play on Google Finance and being a portal and not a search engine.
The deal is, Google has for such a long time, repeated that they are not a portal. The word portal, in Google's eyes, seems to be taboo. Danny, as do many in the industry, feel that this is just downright funny. Either say you are a portal or don't do portal like things... Or is it not that simple?
Danny's thread goes deeper into this long standing conceptual debate.
