Hi Lawrence Duff. Appreciate your interest in SharePoint hub sites, and sharing your take on where we are at their initial launch - a true first offering of cross-site awareness out of the box. The good news is that we are in an era of "service" not "product" and the speed of visible innovation will delight you. Even with a peak of your interest, mixed with your feedback, the team is hard at work with our next set of refinement announcement that we will share this year at the SharePoint Conference (May.2018) and Ignite (Sept.2018). This maintains our cadence of growing the mobile and intelligent intranet, where the true modernization of SharePoint began to take hold ~ 2 years ago. And my ask to you is to consider the progress since then across all primary SharePoint assets, plus the addition of new components, capabilities and apps. Hub sites have a bright future among all the build blocks of your SharePoint-based intranets; group-connected team sites, communication sites, hub sites, SharePoint home, SharePoint mobile apps, personalized search, team news, pages, web parts, integrations with PowerApps and Flow - Microsoft Stream - Yammer - Microsoft Teams - Planner, the SharePoint Framework brings significant improvement to client-side development, improved performance and stability, and much more. I showcase this short list in hopes that you consider the breadth of what the team is offering and responding to (based more so on customer feedback than ever in the nine years I've helped manage our product), and the depth of feature capability over time as they refine, listen and innovate. We have a lot of listening channels, some like UserVoice for the engineering connection and feedback, some like the MS Tech Community, some like Twitter and Facebook, some like face-to-face at events, some go direct in email, some submit from directly within the product - and I can introduce you to 900 people who listen - with big ears and good brains like Jeff Teper at the helm crafting solid deliverables with an equally solid team that gets better and better over time. It's all about the journey, and we're never finished.
Keep the eyes open, more to come quarter-over-quarter. And please, keep the feedback coming on the service as you see it.
I foresee delight in your future assessment,
Mark
