1. A computer-implemented method of enabling users to subscribe to content in a computing environment without initiating a subscription process, comprising: identifying a content access behavior pattern of a user; responsive to the identifying, consulting a mapping that associates content access behavior patterns of users with corresponding candidate content subscriptions to be offered to users exhibiting the associated content access behavior patterns, thereby determining a selected one of the candidate content subscriptions which corresponds to the identified content access behavior pattern of the user, the selected one indicating a subset of content generated by a content source; offering, to the user on a graphical user interface device, a subscription to the subset of the content by rendering a subscription interface for the subset, the subscription interface comprising a Web page which is distinct from a Web page usable for rendering the content generated by the content source; responsive to acceptance of the offered subscription by the user, storing a trigger document associated with the user and the content, the trigger document specifying at least one condition associated with the subset; and subsequently evaluating a then-current version of the content generated by the content source, using the at least one condition specified in the trigger document, to determine whether a then-current version of the subset of the then-current version of the content is considered a match to the at least one condition, and if so, automatically sending the then-current version of the subset to the user as subscribed-to content of the subscription and also scheduling an interval of time on an electronic calendar of the user, wherein the interval of time is specified in the trigger document along with an indication of when the interval of time can be scheduled on the electronic calendar.
