A computer-implemented method, system and/or computer program product manages data in a webpage. A processor receives an input to an input box located in a first webpage on a first network. This input is analyzed to determine whether there is match between a subject topic of the entered data and a first interest window on the first webpage, where the first interest window is reserved for data entries that are described by the subject topic. In response to a processor being unable to determine the subject topic of the entered data in the text entry box, the processor creates a new interest window in the first webpage.
