I wasn't going to go out on a limb but since a comment has been made...
That would be incredibly annoying...
...I would like to address that.
I performed over 20,000 reviews total in about 20 queues at 4 different sites. I am well above Steward badge limits in 4 queues and continue reviewing in these (primarily because it goes so easy), and in any other queue at all.
- And all of my experience has been that "Skip" makes a wonderful grease, allowing one to avoid getting burned out when doing large amounts of reviews.
I aim to act on review when I can clearly explain to self what the post is about and what review action is desirable for it. Apparently, this is not always the case (typical example is when post is out of my area of technical expertise).
- What else but Skip can let one get out of such a deadlock? clicking on a randomly guessed action, like robo-reviewers do?
But getting out of total deadlocks is not the only case where Skip is incredibly useful, I'd say not even the most frequent one.
It often happens to me that evaluation takes more time and effort that is comfortable, review queues contain substantial amount of posts that aren't really clear cut for the action. One option in cases like that is to keep trying to grok it, frying my brain until I am ready to act.
How long can it take, 5, 10, 20 minutes? what's the use of it if after such a brainstorm I am tired and unable to do quality reviews anymore and just looking at review page makes me sick? how much is it better than total deadlock described above, does a single extra review makes it better if I can't go on anymore...
- ...is it worth it? Of course not, and here, Skip is the way to go, I bet all 20K reviews I've done so far.
"But wait!" I hear you say. "That post you skipped, it's out there in the wild and is not taken care of, orphaned and forgotten." This is, of course, nonsense.
In active review queues, there are always other reviewers to pick it after you, either better qualified or simply less worn out, maybe even because you cleared the road for them by quickly working out more items off the queue.
In low traffic queues, the post will eventually return back to you again... but (and this is a very very BIG BUT) it ain't gonna be like first time, trust me.
First time opening a post for review, I am a little bit anxious, because I don't know what's there. But when there's post I already seen, it's a relief ("hello buddy I know you!") and this really helps a lot in getting your brain ready for a harder work. Also, if you think of it, the very break between encounters increases your chances to get to decision, compared to permanently banging your head against that post.
Combined with lowered anxiety, this break does wonders to my mind, I often find myself wondering what made me stuck at prior time, as things look really clear and simple. And, in rare cases when it still doesn't work out well, the way to go is, as usual, Skip.
- Skip is what lets me do reviews instead of frying my brain. Only filtering 1, 2, 3 has more impact on productivity than using Skip.
Skip is... "incredibly annoying"? give me a break. The only reason I can see for someone to honestly think like that is Dunning–Kruger effect.
