Should we mark these somehow, so that we can find them more easily?
I don't see anything wrong with creating this tag as it seems to already have the critical mass to be used appropriately. I also think that the MATT is good for this one (I got 18).
Moreover it will give us a chance to review the questions and maybe sort out a few not so good ones. While editing, keep in mind not to flush the homepage with 150 odd questions at once.
It would be very much appreciated, that you write a tag usage and a short entry into the wiki, if you choose to create the tag.
