Lidiya, да, это правдо.

Thank you very much, Dolvet :) So it was the phrase in the beginning that put me in difficulty. Now it's all clear.

"Мудрствовать лукаво" means to intentionally spend time on wise/philosophical arguments which have nothing to do with reality or cannot solve the problem in hand. Basically, to waste time. What I am trying to say is that "there is practically nothing special left in this subject which deserves wasting time". Some examples: http://dic.academic.ru/dic.nsf/michelson_new/6178/%D0%BD%D0%B5

"Тут мудрстовать лукаво" - "Here, to get wiser vixenly", "особо не о чем" - "nothing special about (it)" ? "There is nothing special to get wiser about, here"? This is what I don't understand :)
