The Portal Example

Remember the early days of the Internet? Everyone wanted to be a "Portal" and become the one stop destination for as many users as they could get.

These portals were unable to fulfill the needs of their users as more focused niche players entered the fray and users began to go to the niche players directly. Monster filled the job search void, Expedia the travel, Buy.com the shopping, etc.

Could this happen again? Of course.

Many more nice players will pop up, some will do a great job at organizing data better than the big boys and then and become big themselves.
