TL;DR There is no short cut to business growth; hacking or not! It takes good effort, consistency, and innovation to build a business that can stand the test of time.

By @Uchechi Ann O. [ 6 Min read ]

At the risk of sounding like the bearer of bad news, “growth hacking” is a mirage that will crumble your business before your very eyes.

Memecoins are Culture Stress Tests — and Thats Why They Matter

TL;DR Memecoins aren’t just jokes — they’re stress tests for crypto infrastructure and culture. Here’s why every builder should be paying close attention.

By @MichaelJerlis [ 6 Min read ]

Poll Of the Week

Slim & Sleek: Worth a Premium Price Tag?

With the recent launch of the Samsung Galaxy S25 Edge and rumors of an upcoming ultra-thin iPhone 17 Air, both at around the $1000 price tag, slimmer smartphones appear to be making a comeback in 2025. This trend is sparking discussion about design priorities and potential trade-offs, especially in the price-function correlation. Would you pay extra just for a significantly thinner and lighter design?

Thinness is a luxury feature I value and would pay more for.
Maybe if it also feels exceptionally well-built and premium.
No, slimness itself isn't worth extra money to me; features matter more.
I'd expect a slimmer phone to cost less if it has a smaller battery or fewer features.
My budget is the main decider, regardless of how thick or thin the phone is.
