Seems like it's a lot of things. Validation, attention, but mostly lack of understanding. There will always be a never ending amount of folks that will get a few tattoos and have them be all they ever get; they won't be "in it" because they have a different relationship with tattoos. And they don't want to be covered and they don't get all wild-eyed and nerdy when someone mentions other tattooers or a rare book or whatever gives the average LSTer a halfie.
So when people show off a little under the cover of asking "what to do," all you can do is either ignore it or give em a quick and succinct answer. "Looks good pal, keep it up," or "Best to go talk to whoever tattooed you, since they'll have a much bigger reference library than your google search," or just ignore it completely. Not worth gettin all worked up over <--..constantly trying to practice what I preach.
(Also, when I started getting tattooed at 18, I'm sure I made all kinds of obnoxious rookie missteps -- like, getting the tattoos in the places I did -- so you can't be too frustrated. Hard though when it's every day with the same nonsense, so I share the frustration.)
