I'm not sure if this is appropriate, but getting conversation representation and message sorting right is the largest focus of my passion project, Ametha.

It would be amazing if I could have a 15 minute voice call with you to hear about your experiences with online communication & collaboration?

The offer is obviously open to anyone else here as well, but no pressure at all, and apologies if HN is not the right avenue for this.

Edit: Feel free to use the email in my profile
