WHAT IF I STORED DATA IN MY MOUSE

A curious idea led to reverse-engineering a Logitech mouse's HID++ protocol using Rust in an attempt to use its flash memory as a portable USB drive. While the goal of truly persistent storage across power cycles was not achieved, the exploration allowed for 2 bytes of persistent data to be written via the DPI register.

YOUR NEXT CUSTOMER MIGHT BE AN AI AGENT

Per-seat pricing doesn't make much sense when your next power user doesn't have a pulse. Charging for software access breaks down when the "user" is an agent doing work autonomously, and the shift toward charging for outcomes delivered is already underway. Founders who don't rethink pricing for this will get undercut by those who do.

HOW I SCALED WARP TO 500K WEEKLY ACTIVE DEVELOPERS IN 2024

Warp grew to half a million developers using its product by 2024 through its YouTube channel, GitHub READMEs, Google ads, and sponsor hackathons that marketed to the judges. None of these were obvious channels when Warp started using them. The best growth channels are the ones nobody is talking about yet. Find an untapped channel, run it hard, and move on when it saturates.

PLATFORM COUPLING: HOW SOCIAL LICENSES & PARTNERSHIPS SHAPE AI VISIBILITY

Licensing deals and ownership structures now shape which social content gets cited by AI models, a dynamic described as "platform coupling." Data from 45.2 million citations shows tight concentration patterns, with ChatGPT citing Reddit for 59.5% of social sources, Google AI surfaces favoring YouTube at up to 74.7%, and Grok drawing almost exclusively from X. Reddit is the only platform cited at meaningful volume by all 10 AI models tracked, largely due to parallel licensing agreements with both OpenAI and Google.

RETAIL MEDIA'S DURABILITY IS TESTED AS EASY GROWTH FADES

Retail media growth is slowing as the industry transitions from easy expansion to maturity, with IAB projecting 12.1% growth in 2026 compared to previous years of rapid acceleration. Most growth has come from reallocating existing trade and shopper budgets, with industry estimates suggesting 30 to 60% of retail media investment originates from these funds, but this source is now drying up. Future growth requires attracting incremental media budgets and solving complex challenges around measurement, particularly proving incremental sales versus capturing existing demand.

HOW DO JOURNALIST RELATIONSHIPS IMPACT EMAIL PERFORMANCE?

Building relationships with journalists drives far better email performance. An analysis of 1.3m emails showed warm outreach achieves a 56.4% open rate and 20.1% reply rate, compared to 38.4% and 1.06% for cold outreach. Recency matters because journalists who replied within 90 days are about 30x more likely to respond again, but engagement is still higher than cold outreach after 6 months. The results were consistent across 17 agencies, with some seeing reply rates up to 40x higher when relationships were strong. Simple tactics like sending relevant pitches, reaching out without an ask, and responding quickly help build and maintain these relationships.

WHY TOO MANY MICRO-CONVERSIONS HURT PPC PERFORMANCE

Tracking too many micro-conversions as primary signals in PPC campaigns can degrade performance by shifting algorithmic bidding toward high-frequency, low-value actions. In some accounts, micro-conversions outnumber real conversions by a ratio of 500 to 1, causing the system to chase cheap signals while actual revenue stagnates. Value-based bidding helps, but cannot fully override signal imbalance when low-intent actions dominate the optimization math. The recommended approach is to limit primary conversions to one or two high-intent actions, use a 25% safety discount when assigning micro-conversion values, and transition to revenue-based optimization once campaigns reach 30 to 60 real conversions per month.

YOUR WEBSITE STILL MATTERS. HERE'S WHAT TO PRIORITIZE NOW.

Websites still matter, but their role has shifted to shaping LLM outputs and converting fewer but higher intent visitors. LLMs now influence research, so site content must be structured for both humans and machines. Conversion is more critical as traffic drops, yet only 12% of teams run A/B tests despite 71% saying they prioritize conversion. Vague social proof performs poorly, so brands should use verifiable and detailed proof. High-performing sites lower friction by using AI style inputs, templates, and clear migration paths to turn visits into action.
