I hope they outgrew it!! but at one point our youngest kid dragged us to a live
Metallica concert... And we used to hear very loud
Rammstein lyrics from car stereo... and had a bunch of corresponding T-shirts.
That made me think of 2 more U.S. usages of the word "swag":
Kids come to someone's birthday, bring cards and gifts, and every guest receives a "swag bag" with identical small gifts
Celebrities gather for en event, and some people receive gift bags with free samples -
example.
As to Andy's question, which promotional merch was most useful to me, that would be a
Bloomberg-branded high-quality black umbrella that had wind vents, lasted for years, and looked good too.
Other examples of promotional merch that displayed someone's promotional logo and that I appreciated and found useful over the years:
* clothes such as t-shirts, baseball/golf hats, or vests (Patagonia no longer does corportate vests, but there are much better choices out there)
* drawstring knapsack / tote bag / duffel bag / banker bag, beach or gym towels, lunch bag, luggage tag
* pocket protector / card holder
* touchscreen stylus . Fancier ones include flashlight or a laser pointer.
* squeeze balls / fidget toys
* mugs and bottles
* mouse pad with wrist support. Maybe even a wireless charger
monitor mirrors
* folding purse hook / hanger
* Tide To Go stain remover pen, lip balm, hand sanitizer
* I am not a fan of anything electricity-related, although something like a popsocket, or a USB powered light or fan, or an external battery, might work
* tchochkes that are less useful, but may look cute: pennants, decals, lapel pins, stickers, fridge magnets, stationery
(this is a working Galileo thermometer)
(this is a working abacus)
(Newton's cradle)
(brain teaser puzzles)
Basically, much of what thinkgeek used to sell before they closed.
The above merch might be great to given away to everyone who shows up to an industry event, or is willing pay a few dollars for mail order.
But, in the context that Andy and Ken first brought up - rewarding people for good answers in the forum - I think an even better reward might be an autographed book. Something like "Volatility Cube" (book title made up), inscribed by the author - "this book was presented to (recipient) for a good answer on QuantNet". I'm not sure how expensive this might be, though. Another possibility might be a glass "tombstone" engraved with the Q&A.
