good idea, she could perhaps do what nerina pallet does and have an @nerinapallot which her manager/record company use to promote her & gigs etc and then have a personal account for her day to ramblings. 
actually they could totally vouch for her not sleeping her way through life by saying stuff like Delta was in the studio with Gary Clark and Nick or Vince or Stuart Crichton (If he shows up on this album I'm flat out not buying it, end, he ruined Believe Again IMO) or Bloodshy and Avant or Cathy Dennis or whoever.
I'd have one for like, musical information, behind the scenes "Sneak peaks", Lyrics sampling, all that kind of stuff, Gig information, Tour information..and another random account she can "Connect" to her stans like it's going out of fashion.
Or at least someone should tell her how terrible she makes herself look by not showing shit on her twitter account, one implication of songwriting (Once a month) is not enough in the world we live in right now. Either accept this change in the world or delete the twitter and do a journal on her website every couple of days to show off her art. (Or even once a week, with lots of info/excitement/passion/sampling et cetera)
TL:DR she needs a better manager who can call her on her shit and MAKE her show people her art, make her record covers for her fans (and put them on twitter), make her want to tour more then once every era (Mention this on twitter), and cover for her when she's not playin' the game (Mention good shit on TWITTTTTTTTTER).
It's not that hard to say:
I was writing today, a song called The Dangers of Living Loose, it's about how controversial my love life has been. Looking forward to it fans?..I am!!!!!!ONE!!!ELEVEN!!!

I mean I know she puts stuff up once a month maybe, and people have attested to that, but from my prospective, as I have said many many many times before it looks like she's just having holidays instead of working, writing, talking to important people, performing, practising, finding a band, discussing possible promotions with album.
Her twitter gives me the shits and I might just unfollow it if we don't get a date by March.
I wrote those fictional dates in about 5 minutes, it 5 minutes every day to prove she's working and give people who don't stan for her non-stop reason to support her and be excited and give a fuck (and keep haters quiet too)
