BTW, if you'd like to get some more free UX feedback, please feel free to visit our UX community platform at https://usability.testing.exchange
You're correct that so far we've been commenting when the person we reply to, can get more feedback about his/her stuff, at usability-testing-exchange (UTX). And, in cases when we've posted lots of helpful feedback, and also a link to UTX, then people have appreciated it, said thanks or upvoted, and some of them went to UTX, helped others over at UTX, and got even more feedback back him/herlself.
In this particular case, though, the actual feedback is brief — about the same length as the "see UTX" line. And I understand that that doesn't feel good.
I think we should write lots of more more helpful feedback, than the text occupied by the "see UTX" line. Look at my other reply (with feedback to OP) on this page for example.
About providing value (which maybe we didn't do so much this time): The purpose is to 1) help the people we reply to, so they can improve their websites & software. And 2) to slightly slightly improve the quality of the ShowHN submissions (feedback —> impovements, better submissions), which I would think is good for the readers here at HN. And 3) making people aware that UTX exists.
So this is supposed to be good for everyone: 1) people who posts ShowHN:s, 2) for the readers here at ShowHN, and 3) for us/me.
However in this case, as mentioned, the "see UTX" line seems a bit distracting and promotional, because the actual feedback is so brief. We shouldn't do like that in the future.

Sorry @dpandya (original poster) for this off-topic discussion from your point of view. Anyway I guess you're interested in feedback about your service? (Since that is one of the points with ShowHN, right.) — I gave Emphasize a try, and left feedback in another comment here.
