1. A method comprising: executing computer instructions upon one or more computer processors to perform the following: determining a first online context of a user, the first online context of the user being based upon a first online presence of the user; storing, in a database, trait information for the user, the trait information for the user being different from the first online context of the user; determining an online context of other users, the online context of the other users being based upon an online presence of the other users; comparing the first online context of the user to the online context of the other users; storing, in the database, trait information for the other users that have entered the first online context of the user, the trait information for the other users being different from the online context of the other users; comparing the stored trait information for the user to the stored trait information for the other users to identify a first group of the other users that share the first online context of the user and at least one trait with the user; enabling automatic presentation of a user interface to inform the user of at least one member of the identified first group of the other users that share the first online context of the user and at least one trait with the user; and dynamically updating the user interface, in response to the user switching to a second online context, to inform the user of at least one member of a second group of the other users that share the second online context of the user and at least one trait with the user.
