There's an undeniable dark sensual undercurrent = Don't you people ever think of anything else?
I'd question your rhymes in lines 2, 4, 8, 12, and 14 = you rhymed an identical final vowel-final consonant pair. I believe the best rhymes are pairs such as "tart/moot", or better yet, "snow/biscuit."
I'm sorry, but this just isn't Deep End material = I don't know you, do I?
This is very fine = I know you, I'm pretty sure I'd better like this, and I have nothing to say, really - hence the use of the adjective "fine" that is never used this way outside of poetry boards.
This is one of your finest poems = I know you and have hated your other drek for years, so it's refreshing to really mean it when I kiss up to you for once.
Amusing, wry, witty, clever, but not truly fine = I really like this, but I don't know you
This admittedly slight piece = I like this poem, I don't know you, but I've got something positive to say about the poem, and I want to do so without pissing off the Truly Fine.
Congratulations! = Why bother with a crit? I'm tired, it didn't suck too bad, and we've been in the same circle jerk since '92.
Thank you for the insightful read = you will die now
You make a good point = You are truly a gibbon among tree sloths, in this meeting of the mindless we call a thread
Thanks for taking the time to comment = although somehow I think it unlikely that you have trouble clearing out your hectic social schedule
You've got a finely attuned, natural ear = (and the intelligence of lichen)
This reminds me of something Sam Gwynn once told me = I know Sam Gwynn I know Sam Gwynn hey everybody I know Sam Gwynn
Just my two cents = I can't go on yammering about this rot without end, Jesus, just take the point and move on
I've taken the liberty of fiddling with some lines = you almost found your voice there - thank GOD I was here to get you to what you REALLY want to say
