Re. the debate re. whether Mazzy Star is doing their own FB postings, etc, Emma may be right the band may have someone still helping them post to FB even though they're not touring & presumably would have time enough on their hands to do it all themselves if they wanted to.
Because now I see times shown when postings are made to FB seem to give a clue it might be an office person during office hours doing all or most of them. Of the last eleven postings, ten were made in a very narrow time window between 2p.m. & 3p.m.(North American Pacific Time) as if someone in an office devotes that section of a work day for it, assuming they may be in North America, & not posting at night in Europe. The one post that's out of that time window was the Dec. 22 new song video with the "seasons greetings" message posted around noon, I suspect Hope wrote. Maybe she posted that one on her own time.
In the early part of 2014, most FB posts were made in another narrow time window of approx. 10a.m to 11a.m., plus a few in the afternoon. The one post Hope put her name to re. Keith Mitchell's Monitor band L.P. is odd one out time-wise again, being the latest post of 2014, just after 4p.m.
I picture musicians, especially ones that travel between North American
& European time zones as Hope reportedly does, & maybe David less so, as not likely to keep such regimented hours for doing their FB postings! So maybe Emma's right about some management person likely doing most actual FB postings on the band's behalf.
But even if someone's helping them with their FB page, I still like to think the band likely
tells their helper what to post, & wouldn't let them freelance in messaging or other content. From what I gather about their personalities, I suspect Hope & David likely wouldn't want to relinquish that control!
