I have both. But my youtube account is now linked to my yahoo email. Perhaps I should have changed it to link to my gmail account (or maybe it is now). I've just had the yahoo one longer. Gmail is mainly for my mailing lists. Since reading those on yahoo is, ..., well, ..., a chore. As in no threading. Each email is individual and sequenced by it's order of arrival or origin. A PITB when that origin is delayed by a month. So I'm generally a month behind reading my mailing lists so those late comers are within the batch of not yet read emails. (most of the time). Further confused by euro versus us differences, i.e. mm/dd/yyyy versus dd/mm/yyyy.
