12. A tangible machine accessible medium comprising instructions that, when executed, cause a machine to, at least:
access a first cookie storage location of a first browser;
access a second cookie storage location of a second browser;
locate a most recently used cookie from a plurality of cookies stored in at least one of the first cookie storage location and the second cookie storage location, the most recently used cookie to identify a current usage activity associated with the computing device;
parse the most recently used cookie to identify an identifier;
compare the identifier to a cookie table, the cookie table mapping cookies to panelists;
when the identifier of the most recently used cookie is associated with a corresponding panelist in the cookie table, associate the current usage activity of the computing device with the corresponding panelist; and
when the identifier of the most recently used cookie is not associated with any of the panelists in the cookie table, associate the current usage activity of the computing device with a guest.
13. A tangible machine accessible medium as described in claim 12 , wherein the instructions, when executed, cause the machine to at least one of create the most recently used cookie, modify the most recently used cookie, or delete the most recently used cookie.
14. A tangible machine accessible medium as described in claim 12 , wherein the instructions, when executed, cause the machine to identify a first type of the most recently used cookie as indicative of a specific web-service.
15. A tangible machine accessible medium as described in claim 14 , wherein the instructions, when executed, cause the machine to identify the web-service as at least one of a social networking service, an e-mail service, or a banking service.
16. A tangible machine accessible medium as described in claim 14 , wherein the instructions, when executed, cause the machine to:
scan the computing device at a second time after accessing the first and second cookie storage locations for a second cookie having the first type; and
detect if the second cookie was modified more recently than the most recently used cookie.
17. A tangible machine accessible medium as described in claim 16 , wherein the instructions, when executed, cause the machine to use the second cookie to identify the corresponding panelist.
18. A tangible machine accessible medium as described in claim 17 , wherein the instructions, when executed, cause the machine to associate current usage activity of the computing device with the first panelist when the user identified by the second cookie is the first panelist.
19. A tangible machine accessible medium as described in claim 16 , wherein the instructions, when executed, cause the machine to associate the current usage activity of the computing device with the guest when the second cookie is devoid of an indication of any of the panelists.
20. A tangible machine accessible medium as described in claim 12 , wherein the instructions, when executed, cause the machine to scan the computing device at a subsequent time for a second cookie having a second type and an indication of modification more recent than the most recently used cookie located at a previous time.
21. A tangible machine accessible medium as described in claim 20 , wherein the instructions, when executed, cause the machine to use the second cookie to identify the corresponding panelist when the second cookie was modified more recently than the most recently used cookie.
22. An apparatus to identify a current user of a computing device, comprising:
an activity associator to identify current usage activity associated with a most recently used cookie; and
a cookie manager to:
access a first cookie storage location of a first browser;
access a second cookie storage location of a second browser;
