Off course !!(And I am certain you knew it !!)
I am all for it, because I think that way we will have more people actively participating in it and trying to answer the questions, than the usual group that seem to be involved in this thread ATM.
I would only suggest we start it as a new thread in such an event, and leave this thread be to run its own course !!
I think this thread in its current format is still viewed by a lot of people who visit the forum (and who obviously read the questions and answers).
Only the questions being vague and sometimes obscure or occasionally hard has without doubt deterred people from making even educated guesses !! (I hope more people will consider posting guesses even - just so we know a lot of visitors are attempting to answer the questions).
Another suggestion would be to try and post questions that more people can attempt (with the intention being to get greater involvement), if one cannot post any question, rather than deliberately avoiding to post questions that we think people might answer !!
Because to me the thrill of this thread is in finding a person who attempts to answer your question or even contemplates your question as worthy of his participation !! (Not trying to show that I can post a question with the help of some books and search engines, wording it in such a way none can even get a hint)
In fact if no-one comes close, I find it enjoyable in giving clues , so that some one will gain some pleasure by using the clue to get to the answer( the example is SJS's question about Macauley- see previous pages, where Sudeep used the clues to get the answer - commendations to both for that exercise ), rather than making out that no-one comes nearer to my unique way of thinking or my superior knowledge !!
I am only making these suggestions because, if you visit the early pages of this thread, the participation was very active and involved a large number of people answering a question. I didn't answer many then, because most were answered by way of clues (which the questioners generously gave to keep the interest active- BI can vouch for this too ) [Does not seem to be the case anymore (I regret to say), where the thrill it appears to me, for some of us, is in One-up man ship and trying to make the questions exclusive !! So only a small number can even try it.]
