Personally, I am missing the discussions from the regular, daily contributors as well, but I really can't blame them for leaving. For many of us, the quality of the show has really gone down in the last two to three months. Honestly, there wasn't much to analyze and discuss during the judaai phase, esp with the makers putting such a big emphasis on KeDi in that track. We wanted to see Sameer's bonding with Rohan and Vishakha, but we never got it. Still, I remember, we were trying our best to analyze certain scenes that were good, and Nivi and others were still making daily posts at that point.
I think once the college track started, it's like Minu said, the suspense/build up of the story hasn't been so convincing (my opinion) and the way the tracks are starting and ending, it's just not living up to expectations.
I will say that this week seems to be a turning point - it looks like the story is moving ahead, and the fun aspect/old charm is still there in gang scenes. I still love Samaina and really want to see justice done to their love story - we'll see how it goes from here on in the show, and hopefully there will be more aspects to discuss.
