I don't think LoD was particularly tit, it's just one of those shows that needed wrapping up, and they did. I've enjoyed it this year as it's given me something to talk about at work (just like I'll be watching Peaky Blinders again, even though I didn't think the last season was that good). Most series peak before they end , hey ho. At least Adrian, Martin and Vicky were great in Velebrity Gogglebox this year.
As for Jack and her life skills tweeting, that was never about being interested what other people think are good skills to teach. It was about her showing her maverick list. It's not like she asked SB what he'd like to do, it's all about her being able to talk about her budget cooking things and sharing that on Twitter
