"NABC seems to have fixed that vexing problem and made this cartoon irrelevant". Well, it may seem irrelevant at this point, but I wouldn't rush to make such statement since Kallol will be hosting NABC2010. Who knows it may be more relevant.

I will with the following statement :
"1. Cut down the number of artistes from India (Kolkata, Mumbai)."
However, I would like to add that NABC2010 organising committee should only invite new comers and not the old "hyped" performers like Srikanto Acharya, Indranil etc. 

2. I also agree with your other points of engaging younger generation with innovative activities (not the speed dating).

3. However, I have little different view points of giving more coverage to litterary activities like recitation, seminars etc. I don't necessarily agree. Unfortunately, the reality nowadays among the NABC organisers are somewhat like Durga Puja's in Calcutta. Who can spent more money and bring all the the latest performers from Bombay. The focus is more on the bells and whistles and it should be that way. Without that no one will come. So, whether we like it or not, this is the reality.
I think it would be better and will serve both the purpose to have more visual actitivities like Drama (good bengali drama), Old movies, Dance Drama of Rabindra Nath Tagore performed by celebrities etc.
