Ukuleles are consumer products. New brands and models pop up, older ones are discontinued, or common problems can arise with an existing model after it's been played awhile. Hence, a 3-month-old thread may be full of outdated information.
Sometimes, too, a question involves more unique concerns than would be apparent at first glance.
Personally, I may grow weary if I see essentially the same question asked several times, several days in a row ... but I see that as my cue to wander off and do other stuff (unless it's the same person asking over and over again, but that's a different kettle of fish).
