Point being: before anyone else stumbles across it. If you wish for others to see your discovery, you should share it with the public.
Of course, that also means you'll have to find something that's of interest to others. Or just upload the data, and maybe someone who analyses it will find that it's more interesting (to them) than you thought.
But otherwise, if people would just stumble across your finds, they'd have to be in frequented areas.
I wouldn't say it's a fruitless venture though: rather, the low-hanging fruit have all been picked clean. You won't find any AFG main stars unvisited around real nebulae, for instance, but if you don't mind climbing higher up the fruit tree, there's still plenty of KM and below to be had. Of course, finding an ELW in a code D system takes much less time than finding one in code B does, but the latter's ELWs tend to be (arguably) more interesting anyway.
But exploration does have an aspect of racing to it, and the easiest stuff has been picked already, so you either go after the more "difficult" systems around areas of interest, or go wherever and hope that it'll be of interest later. You never know.
Oh, and hey, now I'm curious too: when was the last time anyone here has come across my tag?
