I think I could join the Home team as well, at least for now, as I started using it a month ago and have been having a blast. I also have some home-services to upstream after a bit of polish (Guile EDSL for Herbstluftwm configuration if anyone is interested), and some plans to work on the documentation.
I found the documentation to be a bit confusing (understandably, as its new), but once the workflow snapped together its been amazing to see how easy it is to create new services. And I now I have my entire desktop environment contained in a single text file! Being able to ftp a text file to a fresh Debian linode and get to work with all my tools ready within 10 minutes has been magic.
It also demonstrates a lot of Guile's strengths in one place: you can easily wrap interfaces in Guile, and the expressive power it adds (at least in the case of a window manager) is immediately evident.
Very excited about it, great work :)
