I've noticed quite a few questions coming in on META that are definitely duplicates of other posts. To the point where I think the titles may have even been almost the same verbatim (ok, a tad bit of a stretch...).
My gut is that this is occurring by users with lower rep and folks not used to the SO experience yet.
What are your thoughts about the Ask Question really be a search for question first, where users enter the tags and title first and then if no results pop up that interest them, they can get the body to type their question in?
I know that after the title is entered, users can see some items that may be similar, but I'm thinking of expanding that to a forced search where they have to see, still need to ask type of thing...
I have nothing against the auto search and use it myself.... BUT, how may duplicates do you see where a user must completely ignore those results and post their question anyways? If the search worked and process worked, we'd get few duplicates.
@Jeff - completely agree + 100.
@TheTXI - A barrier, but its not like a barrier to entry, its just one more thing to say I'm positive my question is not here. I think at the end of the day, folks are a bit lazy and just want to have their question online and that is that.
