Electronic advertisements and other types of electronic information are distributed based on user profiles and in particular, collections of widgets. User profiles may be generated based on a combination of user entered information and information inferred or derived from user behavior and interaction patterns. The use and collection of various widgets may also be recorded by a user profile to determine a user's preferences and interests. An advertisement may be distributed by segmenting a user population according to user profile information and one or more attributes of the advertisement. Users may further interact with the widgets in a variety of ways including requesting additional information about the advertised product or service and/or requesting communications with an advertiser without compromising their privacy.
