A system for providing targeted Web feed subscription suggestions
calculated based on IP ("Internet Protocol") addresses. Web feeds are
automatically suggested to users based on the IP (Internet Protocol)
address of the user's computer system and previous feed subscriptions
made from other computer systems having similar IP addresses. Feed
suggestions may be weighted based on differing levels of IP address
similarity, in order to reflect differing levels of geographic proximity
between users. Users may be permitted to expressly indicate which of
their feed subscriptions are to be made public through the feed reader
user interface when they make subscriptions. In response to such user
indications, the disclosed system passes the IP address of the user's
computer system to the centralized server system together with a name or
other identifier of the feed that was subscribed to.
