I presume this blog (and site) is written purely for US readership? Many articles are peppered with nationalistic "us" and "we" statements that assume the reader's origin. If you aim to be recognised as professional writers, you should take care with this.
Keep in mind that the US population is less than 4.5% of the global total :-)
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
