David started with the typical "four stacks of longish answers, one in each corner" themeless style, but gave himself an added layer of difficulty. Extending an entry in each of two corners — LINKED IN PROFILE and GET AN A FOR EFFORT — forces the four corner stacks to play nice with each other much more than usual. Tough to make a grid work with so much interconnect!

Speaking of work and interconnect, part of me wondered if LinkedIn is here to stay, or if it'll go the way of Friendster. But it seems entrenched ... enough for now, I guess. I think both feature entries work, but I liked GET AN A FOR EFFORT much better. Maybe because I haven't logged into LinkedIn for several months now?
A themeless with this added level of construction difficulty often requires serious trade-offs — either a lack of snazzy answers or a glut of crossword glue. But David was able to integrate a ton of goodies, PALM READER / EVIL EMPIRE, EMOTICON with a great clue about having its head turned, DIRTY TRICK, IT WAS A JOKE, DIARY ENTRY, EPIC FAIL. All with just a bit of minor SGT, EDT glue. Excellent craftsmanship!
Coming from a pharma background, I thought I'd be able to fill in the [Sex drive enhancer …] with just a letter or two. Had to be SILDENAFIL or TADALAFIL! Nope, it was … PINK VIAGRA? That vaguely rang a bell, but I had to look up what it was — ah yes, the drug marketed to women.
As much as I like colorful (pun intended) phrases in themelesses, this one turned me off. Big Pharma marketing can be so evil, pushing people to buy drugs they don't need. There's something so conniving and weird about making this a pink pill. Hard to figure out exactly why, but reading up on PINK VIAGRA left a bad taste in my mouth.
Overall, the grid was well-crafted, strong enough to be POW! quality. But so much of a themeless's impact is personal. PINK VIAGRA just wasn't much fun for me to uncover, nor was LINKEDIN PROFILE. To each their own.
Although, PINK VIAGRA under EVIL EMPIRE is a pretty funny pairing …
