Hundreds of “satellites” instantly form around every popular web service — many supporting services that offer additional features and services to an audience of large portals.
It is known that every major Internet company has its own policy to attract independent developers. This is a mutually beneficial cooperation: it is also beneficial for developers to create additional services for an already ready-made audience.
For example, around the social network
MySpace has already formed an infrastructure of support services: from the design of personal pages to special targeting tools to help the advertiser. Some services are paid, while others earn through contextual advertising.
A similar infrastructure of "satellites" is formed around other popular web services. For example, the Internet has published a
full list of services for Flickr , official and unofficial. It's hard to believe, but this list contains almost two hundred items! Of these, only eight official services, and the rest - unofficial. Listed below are the best ones.
