Of course it matters! I don't think you can be the kind of fanatic she was and just come to your senses. No one really cares about her or the nephew in particular but the way Morrissey does things and allows things to be done there was probably some "note left on the windshield" level event that would keep this section of the site buzzing for weeks.TTY was active from the fanzine days of 2004 right through to late 2017 before ceasing (Central is about 14 months old).
Julia was spotted regularly at gigs, then vanished.
This appeared to coincide with the appearance & increased use of Morrissey Central and then ultimately TTY being removed from advertising and all statements going through SER.
It's pure conjecture to suggest arguments, being broke or feeling put out by another announcement site etc... - we will probably never know.
Does it really matter?
Without trying to sound harsh, her 'story' was not what drew anyone to her site and the gig reports were seldom glowing if Morrissey spoke directly to her on stage.
The information (especially Morrissey quotes/statements) is still accessible and will live on in one form or other
