I don’t think it’s stupid.
a) for any review to be believable it should include some positive and negatives
b) one of the best things UKP has done is kill the rose-tinted vibe so common in other sites.
I don’t come to UKP to get a hard-on: I come to exchange info.
Admittedly there are people who positively swoon over glowing softporn reviews. I personally think they’re shite, and especially or even more so the unfollowable ones (“look at this hot bird I fucked on Seeking”) if they don’t also include practical info that can assist other punters. But it seems we have to tolerate them.
