A method for determining content that is significant to a user within a web page, the method comprising: electronically receiving an indication from a user that the user finds significant content that appears within a web page presently displayed to the user; only after receiving the indication, electronically analyzing, using at least one processor, the web page to identify a set of topics associated with the content that appears within the web page in response to the received indication; only after analyzing the web page to identify the set of topics, selecting, from the set of topics, a subset of topics that characterizes the content that the user found significant within the web page, the topics included within the set of topics that are not included within the subset of topics being topics that are associated with the content of the web page but that are deemed not to characterize the content that the user found significant within the web page; and updating a user profile associated with the user based on the subset of topics; wherein a user profile associated with a user is stored on a host device and updating the user profile is performed by the host device; receiving a request for content from a user; receiving a user identity associated with the user; accessing a user profile associated with the user identity; determining content to provide in response to the request based on information within the accessed user profile; and transmitting the content to a client device for display to the user. 2. The method of claim 1 wherein the subset of topics comprises a single topic. 3. The method of claim 1 wherein the subset of topics comprises multiple topics. 4. The method of claim 1 further comprising determining the content that the user found significant within the web page that is characterized by the subset of topics. 5. The method of claim 4 wherein updating the user profile based on the subset of topics comprises updating the user profile based on the determined content within the document. 6. The method of claim 1 wherein selecting the subset of topics comprises: enabling the user to perceive the set of topics while the web page is displayed to the user; prompting the user to select a particular topic that is related to the indication; and receiving, from the user, a selection of the particular topic that is related to the indication. 7. The method of claim 1 wherein selecting the subset of topics comprises: accessing the user profile associated with the user; determining topics identified as being significant to the user based on the user profile; comparing the set of topics to the determined topics; and based on the comparison, selecting the subset of topics. 8. The method of claim 7 wherein the topics previously indicated as being significant to the user were selected by the user. 9. The method of claim 1 wherein selecting the subset of topics comprises: selecting one of the topics from among the set of topics as a particular topic that is related to the indication; presenting the particular topic to the user while the web page is presently displayed to the user; and enabling the user to veto the particular topic as the topic that is related to the indication. 10. The method of claim 9 further comprising, as part of the veto, enabling the user to identify a different topic as the particular topic while the web page is displayed to the user. 11. The method of claim 1 wherein receiving an indication from the user includes receiving an indication of selection by a user of a content significance user interface element while the web page is displayed to the user. 12.

The method of claim 11 wherein the content significance user interface element is configured such that selection of the element indicates that the user is interested in particular content within the displayed web page. 15. The method of claim 11 wherein the content significance user interface element is configured such that selection of the element indicates that the user is not interested in particular content within the displayed web page. 16. The method of claim 1 wherein analyzing the web page to identify the set of topics associated with the content that appears within the web page comprises: accessing HTML content of the web page; cleaning up the accessed HTML content to remove information that is extraneous to the content actually viewed or accessed by the user; and identifying the set of topics from the cleaned-up content. 17. The method of claim 16 wherein the HTML content being accessed includes all content within the web page regardless of whether the content was currently perceivable to the user at the time the indication was received. 18. The method of claim 16 wherein cleaning up the HTML content includes removing HTML tags or advertising information from the HTML content. 19. The method of claim 16 wherein cleaning up includes performing speech-to-text, optical character recognition, visual pattern recognition, image analysis and metadata inspection techniques to determine the content actually displayed to the user. 20.
