I'm never going to send unsolicited concrit to an author. (Apart from it being rude, I do enough concrit in my day job and have no desire to do it in my free time.)
And I'm not going to post recs with reservations. As in: "the plot is stupid but there are some good jokes." (I might do that if reccing a commercial work, but never for a fanwork.)
I'm going to loosen up about recs. Sometimes I'm going to rec works that I think are flawed but compelling anyway.
(All work has some flaw, right?)
