I've enjoyed corresponding with Daniel. He keeps on calling me "Mr. Chen," which I find infinitely amusing. Sort of like Marcy calling Peppermint Patty "sir." I've appreciated how polite he is with his inquiries, taking care to never infringe too much on my time, so it's a pleasure to see him make his debut.

That SE triple-stack is a beaut. GREAT DIVIDE is a great entry in its own right. GAY MARRIAGE, love it! And the common SEE ATTACHED rounds it out. I'm not a fan of DR T, who doesn't feel crossworthy, or BRAE, which is a bit of an odd word, but those were well worth the price of admission into that corner.
The opposite corner was pretty strong too. I wasn't sure if EROTIC NOVEL was truly a genre, like GOTHIC NOVEL, but some Googling proved me very wrong. Sometimes I forget that romance / erotic novels are WAY more popular than stuff worth reading. I mean, other stuff. Ahem.
I would have liked some of these marquee entries to get clever clues, though. Referencing "Fifty Shades of Grey" for EROTIC NOVEL felt like a let-down, when there could be so many plays on the word "blue."
Some entries must get a definitional or otherwise easy clue — GREAT DIVIDE would be tough to riff on, since it may not be immediately known to some solvers, for example. But entries like EROTIC NOVEL or GENE THERAPY left a lot of great cluing potential on the table; plays on "strands" or "bases" for the latter.
DEMO TAPE was a perfect example of clever cluing hitting the mark. The question mark in [Rock sample?] gave away part of the game, but I still enjoyed the repurposing of a common phrase into a completely different meaning.
There are a couple of shorties I debated internally. LYSIS is common enough in biology, something I heard all the time in my second career (in pharma). Clued as a suffix, it's definitely gluey. But as a scientific word? Hmm. Still probably esoteric for most. EGEST is similar.
Overall, very nice debut! Mr. Chen approves.
