As a rule, I click TFA while it is still in the subs queue. Not always, but that's sort of the rule. Sometimes, a submission is moved out of subs queue, into pending stories, before I read TFA. In which case, I will sometimes copy paste the title into a search. I suppose that I've read about 60% of TFAs before they reach the front page. Those that I haven't read, I may well click on the link if I find the discussion interesting.
