In reply...

In reply to this rant, since I think this is another rant that just happens to touch on the same subject.

To paraphrase what many have said already: No writer is obligated to write you your dream fanfic (although it would be lovely, they're not obligated.) Similarly, no reader is obligated to leave reviews. Writing a fic for someone is a Nice Thing to do. Most reviews (barring troll's flames) are also Nice Things to do.

And you know what? I don't mind the one word reviews. They're not "useless". Generally, they're more honest, anyway. I know that I often look over my own reviews and sometimes adjust wording to make sure it's not an abrasive litany of wrong things. A succint, short, one-word reviews generally consist of the feelings that the reader has upon finishing the fic; this is useful.

You just have to interpret it.

Even the reviews saying "update plz!" are saying something to you: "I like it, I want to see more of this, I think that this story works so well that I can't wait for the next installment," and so on.

Please look up "entitlement." And let me tell you, I was very strongly tempted to critique your rant. Still am.
