I've noticed quite frequently that (especially new) users don't mark answers as the accepted answer, but only comment it. For example just today you have [here](https://stackoverflow.com/a/53465558/3484879) and [here](https://stackoverflow.com/questions/53468555/merge-two-queries-and-having-no-relation/53468725?noredirect=1#comment93808792_53468725).

Accepting an answer as the solution is obviously up to the OP but do answers like these gets accredited by mods/the powers that be? I can understand that this wouldn't be the case if the OP hasn't commented that the question is answered, however, when they comment to say it does and then don't why is a question with a confirmed answer left as unanswered?

This isn't about the points (if you're here just for the points, you have the wrong attitude in my opinion) but for others. When I'm searching for a solution to a question I have, the topics I visit first are those with accepted answers; as those are the ones that are likely to have a solution. I'm sure I'm not the only one who operates like that. As a result, I, or anyone, could miss a very good and informative answer, because the OP has verbally confirmed the answer, but not (taken the time to?) clicked the button.

Perhaps it more a UI thing? Is the accept answer as solution that obvious to (new) members over leaving a comments? I ask very few questions on SO (mainly as I almost always find a question very similar to my own, with an accepted answer and it solves the problem) so honestly I'm not sure; although I'll see the layout if/when someone replies with an answer. Maybe if more people only commented and didn't accept the answers as a solution my experience would be less like that? Unknown.
