The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.
If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.

Simplygon, a simple way to get your content HoloLens-ready
Content for mobile AR/VR apps needs to be extremely well optimized, as you all probably already know.
Simplygon is a platform that lets you automatically optimize 3D content such as meshes and textures for different purposes with no or minimal manual labor. You can use Simplygon to create LOD chains, reduce draw calls, combine several high-res meshes into one cheaper mesh, optimize a scene for certain viewing angles, remove invisible geometry and so much more.
With Simplygon in your content pipeline for your AR app, you can take complex data and compress that into something that not only looks great, but also runs well on your target hardware. Here is a video that shows how a highly tesselated asset is brought into Hololens using our toolset: https://www.youtube.com/watch?v=_RGGV4KUsrM&t=3s
Simplygon was recently released with a new free offer for personal, non-commercial and educational use. You can also contact us to get a fully featured evaluation license, to see how we can help you in your projects.
